High Temp. Tape

If you are having blow outs due to the heat I would think you would want to take the temperature on the rotor. The caliper contact is through the brake lining which insulates the heat.

You may be able to drill and mount thermocouple into the brake lining 1/8'' probe should leave enough pad for test purposes.

if you have any water in the brake fluid or air, as it heats either the air expands or the water vapor makes bubbles that are enough to advance the brake pad so it is rubbing all the time = heat galore.

the wheel that get hot, after they are hot, stop and jack up a wheel and turn by hand...look for drag

replace fluid and bleed brakes properly if required.

The thermocouple can be attached to the caliper surface by welding or brazing, eliminating the need for tape. Alternately, the thermocouple can be installed in a hole in the caliper, thus forming a thermowell. A general rule of thumb is that the thermowell should be 10 thermocouple diameters deep. If the caliper is on a moving vehicle, I would suggest brazing or soldering the thermocouple into a screw that is installed in the caliper. If you want to know the temperature of the brake pad, I would drill a small thermowell in the pad itself. If you use a sheathed thermocouple, remember that insulated sheaths do not have the response time of grounded sheaths. I would stay away from sheathed thermocouples for high speed instrumentation work.

Maybe a high temerature RTV such as Permatex Red silicone RTV. The advertised temperature range is -75 deg F to 650 deg F.

Is it the brakes causing the tire blow outs or is there a bearing heating up agin check for drag. As for mounting thermo couple how about apoxy putty wide temperature ranges available .

Use a clamp
