Modern disc brakes, whether metallic or ceramic, work best when heated, to a point. One reason disc rotor size has decreased is to allow brake heat to rise quickly. Most work well in the 200' Fahrenheit range and continue to work until fade occurs, usually over 400' Fahrenheit.
Parking brakes stick if left applied in cold weather
If you mean that the rear brakes won't work or that the parking brake won't release, it's probably because they are wet and the ice is keeping the parts from moving. If it's the parking brake, dry everything out then lube the cable. If the rear brakes aren't working, make sure the brakes are dry when you park for the night.
I would check switches for faulty sensor on emergency brake...GOOD LUCK
black is power to unit,red connects to cold side of brake light switch,bleu is power out to trailer brakes,and white is ground
Sounds like you may have moisture in the brake fluid. Have your brake fluid totally replaced. Your master cylinder may also be failing. Hold steady pressure on the brake pedal. If it very slowly goes down replace the master cylinder.
My mother-in-law had this problem. Mostly in the morn when it was cold. Of all things it turned out to be her breaks were shot. She had her front and rear brakes were replaced and now the brakes hold the van still. Hope this helps.
Disc brakes tend to dissipate heat better and do not collect nearly as much dust as drum brakes (which traps the brake dust in the drum with nowhere to go), so disc brakes will work better as a rule. Pad wear tends to be more even. Also, the rear wheel cylinders do not rust out and fail as often as with drum brakes.The drawbacks are with discs are:1) When using metal-based pads (common these days), disc rotors tend to warp far more often, especially on the front. They will tend to squeal more unless anti-squeal shims are fitted to the back of the pads.2) Drum brakes warm up faster in very cold weather.3) Loose gravel stones wedged between the rotor and calipers will cause damage.4) When driving through wheel-deep water, disc brakes (especially with metal-based pads) do not work as well as drums until the rotors spin the water off.5) When used as a parking brake, rear drums tend to work better.There is no situation they are better. Disc brakes are superior in every way.When used as a parking brake the drums tend to work better.
a sticking/partly sticking caliber piston is usually the culprit but a froze parking brake cable could cause the rear brakes to heat up also.
It does not make a difference if the car is hot or cold when you add brake fluid.
Brakes dragging? Return ports on master cylinder restricted? As brake fluid heats it expands, if fluid return passages are plugged calipers will expand causing brakes to apply
Use a test light One wire (hot) will illuminate The other wire (cold) goes to the brake lights will not illuminate
You went thru a deep puddle with hot brakes. The disc gets doused in cold water and warps.
