Brake Problem 2003 Chev Silverado 2500hd

I have my suspicions but you really should take this to a qualified mechanic. For all I know you might be that Silverado that follows me in the morning.

no worries repairs are done at dealers and the mechanic cant seem to figure it out and i only drive it 4 to 5 times a month sometimes less .

yes the drag was the reason . now they are saying its the master cylinder this was supposedly determined by a test they did . i have a feeling it may be something to do with the abs system but have not found any one else with same problem nor has the gm dealer where i live .thanks for the info about adjustments may come in handy i will be sure to mention to mechanic.

Use this site to search for brake problems. Should be a few. Stuff them down the throat of the people that took your money. You should not have to diagnose your problems if you are paying a mechanic to fix your truck. Putting a new master on now will allow him to make the adjustments, and tell you it was a bad master. That way he can get paid again. Sorry for your aggravation. Good luck.

I had the lights in the dash stay on .So I phoned the garage and got a young girl .I said I want to talk to a mechanic .She said I can get you a technician .I asked her, Do you know the difference ?, A Technican changes the parts till they finally fix it .A mechnic can fine what's wrong ,then fix it only charging you for the parts needed .

Then she hung up on me!

Sweet!!

Tough economy leading to business diversification.

well i went to the garage and talked with the mechanic about the adjustment info he had already checked for play and showed me .we discussed changing the master instead of the abs unit when he pulled the master it was actually stuck pushed forward. new master installed brakes like new drove 1hour no drag alot better than3 km we had before thanks for the knowledge and the great answers !!!

It is true to say that when all brakes rub, its usually the master cylinder/booster.

If only one brake rubs, there are other well documented reasons why that do not usually involve the master cylinder.

If two brakes rub, usually diagonally opposite to each other, this can be a master cylinder problem too.........

Now all the members here that did not think the master cylinder was at fault and found other strange alien reasons, should think (logically) again!!!!

Master cylinder is faulty in about 90% of such cases.....its the logical part to replace first....

GA. Good post, informative and accurate.

We just did this all for another car recently, then it was also the master cylinder.....the bit that the mechanics simply did not want to change if I remember correctly.....after they had changed out disks, calipers and God knows what!!!!

are you using a good grade of brake fluid? it could be boiling. maybe moisture in the fluid. or the check valve in the master cylinder. if it started after you replaced the front pads, there's your problem.

yes its a good brand of brake fluid when brakes are seized the master is cool to touch when calipers cool down truck rolls freely.

You might try bleeding all of the wheel cylinders and the master cylinder and moniter the booster vacuum if you have one.

An interesting note here.. Most people have no idea the brake fluid does go bad and deteriorates... It's usually a good idea to look at your brake fluid at around 50,000 miles or about 5 years... It's supposed to be clear or have a yellow or gold tint. If it looks the color of your last oil change, time to flush the system...

Geitjie, Do not let that "Mechanic" near your car again.....he is realy stupid! Bob c is right; The master cylinder piston does not move to its rest position or the primery washer in the master cylinder is swollen so that the compensation port stays closed....or this port is blocked...maybe someone put engine oil in the system!
