Depends on the car and what type brakes it has and your level of mechanical ability and your access to tools.

*I* can change *MY* brake pads out quite easily, your mileage may vary.

It is the rear brake of Ford Lincoln Town Car 4 Door 1993.

I think I have the needed tools.

I'm assuming it has drum brakes. Drum brakes require a few specialized tools that are not in most people's inventory unless they have done brakes in the past and they are not exactly the easiest to change out either. I much prefer disk brakes. You'll need a brake spring compressor tool, which looks like a screw driver with a serrated concave cone to grip the brake shoe support spring cap so you can turn it the 90 degrees you need to engage/disengage the retainer "nails".

you'll need a spring tool to pry off/on the retraction springs, and possibly a pair of spring pliers as well (I generally get by with needle nose pliers and vice grips, but I'm sure having the right tool probably helps some.). And finally you'll need an adjusting spoon. you can buy them separately or as a kit. you may also need a puller tool to pull the drum off if it won't come off easy.

Do yourself a favor and once you have the drum off, take a picture of the assembly with a digital camera and print the picture out as big as you can. that way you will be able to remember where all the springs and gizmos go when you put it back together. the two sides will be mirror images of each other so make sure you know which is which. take more than one picture from multiple angles so you know how it all goes together.

first look to make sure the brake cylinder has not been leaking. look for any signs of oil in and around the brake cylinder. if it has leaked, things just got more complicated. you might at this point want to consider putting it back together and visiting a competent mechanic. *I* could change out the cylinder, but I would not want to try to describe it to someone who has never done it. if you screw it up, you could have no brakes at all so I'm just as soon skip that part.

do not breathe the dust! it may be asbestos!

brake shoes are usually sold with a "core" meaning they want the old metal shoes back to reline them and resell them. so you'll need to pack up the old ones after you get them off to trade them back in. I generally like to buy the new ones first, compare them with the ones on the car before i take the old ones off to make sure they will fit (parts men make mistakes too.). if they don't match then i don't have to put the old ones back on while they try to get the right ones in stock. i can just pop the drums back on and wait a week until the right ones are in.

once you get the drums off and you know the shoes will fit, it is time to take the drums to your parts store/automotive machine shop and have them turned/trued up. at this point you may discover that the drum is worn too far and you must get a new drum. the machine shop will have the proper calipers and know how much meat is required for safety. leave the drums for them to machine while you head back to the house to replace the shoes. dissassemble and then reassemble one side at a time and make sure you screw the adjuster all the way in (it is a left hand thread!). that way if you still can't tell how it goes together from your pictures, you have an assembled model on the other side to compare against. this is important enough to repeat. the assembly is kinda complicated, so make sure you do not touch one side until you've finished with the other.

once you get both sides changed out, then go pick up your now machined drums and slide them onto the axles. now you will need to use your adjusting spoon to reach through the small adjusting slot (which may have a rubber plug/grommet in it) on the back side of the wheel assembly and screw the adjusting star back out until the brake shoes JUST start to touch the drum (you can feel the drum start to drag just a little tiny bit as you turn it.).

still up to the task? remember if you get it apart and can't figure out how to put it back together, you won't be able to drive it to your mechanic to get him to fix it. so be ABSOLUTELY sure you feel up to this before you try it. That said, I can do all four wheels (two drum, two disk) in an afternoon if it isn't too dang hot out. it is not DIFFICULT, but it is a bit complicated. Some of those springs are pretty stiff too and can be a real pain in the arse to get back in place sometimes. You need good hand and arm strength for them and the right tools (and knowing how to use them, the bendix tool is not all that intuitive, and you have to remember the adjuster screw is left handed so it works opposite how you expect it to.) really help.

Nice job. I'm just going to add to you're post.

If you are replacing one side, do the other also, at the same time.

He also, and first of all needs to jack the car ** and make it stand safe.

Then remove the wheel.

see handbook "replace wheel"

I just did one for a friend who went to a bush mechanic and afterwards he lost the wheel. Had to order a complete wheel hub assembly and brake clamp.

The bolts had 8 washers each because he couldn't find the original ones back in the dirt. It was a 4 X 4 suzuki escudo, privately imported from Japan.

I had to order the spare parts in New Zealand.

(used)

Took 4 months to reach.

You really took the time to explain it well.

Excellent point! Since the vehicle is a rear wheel drive one, the front wheels freewheel and must be chocked to prevent the car from moving once the rear wheels are off the ground (only one must lose contact with the pavement for the car to roll). setting the emergency brake obviously won't work (and you won't be able to get the brakes disassembled if you do that!) the rear axle MUST be properly supported on jack stands. NEVER EVER support a vehicle on the jack alone. it WILL fall off the jack or the jack may collapse and it MAY kill you, or make you wish it had. I had a run in with a falling jack myself many years ago. I was replacing the front disk pads on my wife's Nissan Sentra (god I hated that car, and the feeling was mutual, I could tell. it was a serious POS and it HATED me as much as I hated it). I had completed the job and had jacked the car up off the jack stands in order to remove them. just as I pulled the second jack stand out, the jack fell over. it fell and whacked me on the head and dislocated both shoulders (it felt like they tried to meet in the middle in front of my sternum) and may have cracked some ribs to boot. luckily the wheels were back on the vehicle so there was some space under the vehicle so it only beat the crap out of me instead of killing me. And of course I was home alone working on the car while my wife had driven to my moms house a few blocks away. and I was pinned.... and nobody was answering my yells for help either. yeah, it was a bad day all around... then when I finally got to the ER, they put someone that must have been dying of viral pneumonia in the bed next to me and she was sneezing and coughing like mad. and of course I was strapped to a backboard and could not even cover my face, so of course a couple days later I got sick as a dog and was coughing and sneezing with cracked ribs and two dislocated shoulders.... GAWD I hated that car.

Good post. GA from me.

He should consider using eye breathing safety equipment as well.

Actually, if he needs to ask and as this is "safety" equipment, we should really say NO to his question.......or we may never here from him/her again!!!

if it is disk brakes they are much simpler and generally all you need tool-wise is a large C-clamp to compress the caliper. Some vehicles the bearing hub is integrated into the rotor which makes taking the rotor off a pain in the arse, it generally is best to replace bearings and seals too with them.

It's pretty easy but if you havn't done that sort of work before a handbook is ahandy, or a friend who's done it before. Some cans af beer are handy, and I usually grate my knuckles before I start, just to save the time of doing it during the job (that's a joke)

It is pretty easy, I've done it several times. It is a two person job though, you'll need someone to pump the brake while you bleed the air out of the lines (change the brake fluid too while you're at it). The fluid is nasty stuff, do NOT get it on your paint!

That is only if the cylinder needs replacement too. I would suggest a mechanic at that point just for safety's sake.

If they are drum brakes, plan on bloody knuckles, getting the springs back in place.

If you want to work on your car yourself, I would recommend,1) getting a manual for your specific vehicle. ( Repair manual, not owners manual)

2) Familiarize yourself with the steps and tools involved in whatever procedure it is.

3) Go for it! ( Slowly and methodically, when removing parts, set them down so you can remember how they go back). This is how I've always done it and I've successfully completed a couple of complete engine rebuilds.

One way to keep parts in order is to take an upside down cardboard box, punch a hole for each piece you pull off, insert pieces in holes, configured and numbered as to how they were on vehicle.

You don't want to pull everthing apart and not remember how to put them back. I've done that also, it's no fun.

PS Doing anything the first time is never easy.

If you need to ask the answer is probably NO.

Since it's an important part of the car's safety system get someone knowledgeable to show you how first time. ffeJ

For the first time find a friend who can help you tell you what to do, You will need a proper bit to pull the calipers. A C-clamp to compress the piston. On the rear you will need a tool to rotate the piston and depress it for the emergency brakes.

Basic hand tools a 3/8 drive ratchet and sockets. Proper sized torx bit and maybe 1/2 drive tools. Jack stands and a floor jack.

I'll second the Guest post at #11.

Brakes are an important safety system on your car. If you are not confident in working with them, leave it to the professionals!

I'll leave you with the short story of a former coworker, an Engineer, who also had some experience working on cars. His girlfriend asked him to change her brakes and he acquiesced. He took the car out for a test drive after completion of the job and crashed it for lack of working brakes. He was ok, but the car was totaled. Needless to say their relationship was totaled as well.

I changed the brakes on my truck one time. I had done it so many times I didn't even really have to think about it.

In my confidence, I also didn't think to bleed the brakes.

Jumped in, started her up and backed directly into a big ditch. Had to call a tow truck to get me out.

Re: Car Brake

myself or yourself? yes and no..

Front discs.. often very easy.. 10 min in the snow..

rear drums.... not so much.. park the car and have the bike ready.

fortunately.. rear drums can last and last

1st time is always the hardest.

sometimes there is rust and hangy metal bits that you have to muscle and bang past, but otherwise.. front disc brakes are about as difficult and time consuming as changing the the tire on most cars and trucks.

add new rotors? twice as tough.

tools needed..

1 big .. 6" c-clamp about $5- $10

1 socket.. maybe 14 mm?.. you might have?

brake pad set of 4.. about .. $15-20+

Don't do it. You don't know enough, and these instructions are not clear or complete. Brake failure endangers both the people in the car and outside it. Sorry.

Buy a shop manual or independent car repair manual for your car and review the section describing how to replace the brakes. Usually that is not a difficult task but you may need some tools. If you don't have the tools and have never changed brakes before, I suggest asking a shop to do the job on the condition you can watch and learn the steps and tools that are needed.

By the way, buy the best premium brake parts you can get. They will cost more but last longer. OEM quality parts can be purchased from a parts shop or on-line, you don't have to pay the dealer's inflated prices.

Lastly, consider rebuilding the calipers (on front brakes) or wheel cyliners (on back brakes) when the pads/ shoes are replaced. And make certain the brake fluid is changed every year.
