Rear brakes overheating - Cars & Trucks

rear pads dont have so much work to do as front are the sliders free might be sticking on a bit so binding.or badly adjusted parking brake so not fully disengaged?

try bleeding the front brakes sometimes the valve will move to one side allowing more pressure to the opposite brake possibly causing this type of problem.

Coincidence. Check brake fluid and master cylinder. Check front calipers for failure, possible deployment and pressing the pads against rotors.

is ther a rear brake equaliser on the rear axle? this is usually spring operated that pulls up on the rear brake limiter depending on load in vehicle may be stuck in the vehicle loaded position when the vehicle isnt carrying much weight worth a look , just jack up rear end and look for spring device centre of rear axle attached to a device with the brake lines entering/exiting if there get vehicle as high as safe to do then put blocks under rear wheels then slowly lower jack and look to see if the spring device moves down with the vehicle if not this could be the problem as is exerting pressure to rear brakes so causing them to over heat keep me posted

At least one of your rear calipers is likely sticking and needs replacing.

Possibly fitted wrong,,,,possibly calliper or slides seized,,,sticking badly

I just find this (click over this link for zoom)...

The rear brakes do not require manual adjustment. Adjust the shoes by sharply applying the brake pedal several times while driving the vehicle alternately forwards and backwards. Check the brake operation by making several stops while driving forward. The self-adjusting mechanism will sufficiently adjust the rear brake shoes without any manual tightening at the brake shoe adjuster. If the rear brake shoes are manually adjusted, the additional action of the brake shoe adjuster can cause the brakes to become over-tightened and result in binding or overheated rear brakes.

Hope this helps.

Do you have drum or disc rear brakes? If drum, the wheel cylinder probably needs to be replaced. If the wheel has overheated at any time, you should also replace the hardware (springs, etc) as they can lose their ability to retract the shoes if overheated. If disc brakes on rear, then the caliper is probably to blame. Has the brake fluid ever been changed? Fluid absorbs moisture (never use brake fluid from an open or not tightly sealed container). After rebuilding or replacing the caliper or wheel cyl. bleed all 4 wheels to flush out old fluid, otherwise you may have other wheels w/ brakes dragging/not releasing. Let me know if this doesn't fix it, I'll help further.

your rear caliper adjustment is made by using the parking brake,if you don't use it on a regular basis it can cause the rear brakes to not work properly or at all.you need to use the parking brake regularly to avoid this.you may try working the parking brake repeatedly to try and adjust the rear brakes,if that works you may notice your brake pedal is higher or firmer.

Have someone push & release pedal while at wheel with problem. See if it takes a while or slow to release. If yes, have wrench ready on bleeder screw, and try again, if it sticks/holds, crack bleeder screw, if it releases, I'd replace hose.
