What causes brakes to seize in their carriers?
Answers:
I assume you mean car brakes and the carriers would be the drums on drum brakes. Most of the time seizing is from heat caused by misaligned or misadjusted brake shoes.
I assume you meant to write why do brakes seize in their calipers?
Usually because of the dirt and grime that get into the space between piston and bore of the caliper.
Brake fluid is also very hydrophillic. It likes water. Which could cause some oxidation between the piston and the bore of the caliper.
I didn't know brakes hung out in carriers.. Please find the proper word and re-ask your question.
Dirt,grime,neglect, age, ect
In my case it was lack of use.
Check in the owners man. for exact free play distance !
Front brakes lock up because the master cyl to brakes do not have enough clearance. Simple remove the master cyl ,,,, do not disconnect the lines just-move forward. A little shaft has a pin with a wrench place and at the end is a nut and locking nut. screw in the shaft about 1-1/2 turns. Reassemble and test the foot/hand petal so you have about 1/8- 3/16 free play.(see man. for exact clearance) Always make sure the master cyl is working once your done. .
There must be free play so the heat of the system has a place to bleed off.
My brakes froze up 2 weeks ago so they replaced the caliber, but it wasn't it, it was actually the master cylinder, I got a new one $70 and now its all better
brakes don't rust there for thay cant seize in the calipers but Ur calipers can seize due to rust
replace calipers
Your question is not quite clear, however if that is what you have been told then go to a different garage. Brake pads do not have any moving parts, hence they cannot seize. They can get stuck due to dirt, rust etc. but any mechanic can replace brake pads it is by no means a difficult job.
The brake calliper (that's the bit that pushes your brake pads onto the brake discs) has a cylinder which can seize. If this is the case then sometimes they can be disassembled, cleaned and put back together. It all depends how bad they are, they may need to be replaced. Hope this answers your question. Good luck
As you say pads and not shoes I assume you have disc brakes and callipers. The pads do not seize in a calliper. The way the hydraulic system works is that when you put your foot on the brake peddle it engages a 'pump' at the top(the master cylinder) to compress the fluid in the line and force the piston in the calliper out and hence push the brake pad onto the disc. It is the pistons in the calliper which suffer seizure and stop your brakes from working. This is usually caused by the dust seals protecting them from failing and a build up of dirt, however lack of use is another major issue and it is possible to heat seize a calliper if they are seriously over used.
As most people have stated one of the main causes of brakes sticking is dust. When the pedal is depressed the pasd are pushed in to contact with the disc, this causes the vehicle to slow and obviously the pad to wear, there are very high temperatures involved here and the only returning force here is the actual rubber seals on the caliper round the piston which when the pedal is relaeased allow the pad to move back. When pads are fitted a very high melting point greas is used (or should be) if the brakes are not maintsine correctly this can cauuse the dust to lodge in the ares where the pads move, causing the pads to stick, over a period of time this can affect the operation of the sliding mechanism of the caliper. the solution is regular maintenance to ensure this doesnt happen and cut down on repair costs as well
