"blistering hot is about 140F" this is normalfor brakes that are used. drums will get hot.when spinning the wheel it should take some force to spin the wheelbut not a ridiculous amount. it should drag veryslightly.


Simply so, how hot can brake drums get?

I have found that good working brake drums shouldattain a heat range of 160 degrees and 180 degrees.Temperatures over 200 degrees lead to brake fade and paintblistering of drums. Anything less than 150 degreesindicates brakes need adjustment or repair and may not beworking correctly.

Secondly, why are my drum brakes locking up? Rear drum brakes can lock for severalreasons. One reason could be a defective wheel cylinder, which ispart of the brake system. Your brake cable could alsobe adjusted too tight. The slightest pressure on the brakepedal, will then cause the brakes to work at full force,causing the lock up.

What is normal brake temperature?

A normal stop from 60 mph can easily raise thetemperature of the front rotors 150 to 250 degrees. Severalhard stops in quick succession can send rotor temperaturessoaring into the 600, 700 or even 800 degreerange!

What causes rotors to get hot?

When you drive heat is generated in the caliperwhich causes the brake fluid to expand. Normally thisexpansion is accepted into the master, but if it is over filledthere is nowhere for it to go so it pushes the caliperspiston out which creates excessive friction between the brake padsand rotors.

How do you cool hot brakes?

Cooling off overheated brakes is simple:Just drive around at modest speeds, (slow enough not to need thebrakes) for about 5 minutes. This will keep the pads fromsticking to the hot discs, and keep the discs from warpingfrom the concentrated heat in the area covered by thepads.

What do you do if your brakes overheat?

You need to let the brakes cool, however,if you leave the car in one position there's ahigh probability that the heat of the pads will warpthe brake rotors. If you can keep the wheelsturning, even slowly, that will prevent warping. Keep it in firstgear so it doesn't get away from you again.
