My Toyota 98 got brakes @ 53000 now @63000 brakes are gone, car x says new calibers needed?

Question

I got four brakes, back brakes are good but Front right side brakes are gone only after 10000 miles. Now CAR-X tells me I need new brakes and two new calipers? what are they up to?

Answer 1

yes your caliber are froze up and try to adjust the rear brake that will
help but there right

Answer 2

Regrettably it does sound as though at least the front right caliper is dragging, most likely because the piston within it is frozen from corrosion in the piston sleeve.

Your brakes operate on an hydraulic system. When you press your foot on the brake pedal it pushes in a large piston on the master cylinder which drives brake fluid through the break lines to smaller pistons on each wheel called wheel cylinders (on drum brakes) or calipers (on disc brakes).

Because the master cylinder is a larger piston and the wheel cylinder or caliper contains a smaller piston, the difference in the size of the pistons results in a multiplier effect on the force of your foot--which is why your foot pressure is able to stop the car.

Now, inside the caliper, as I noted is a piston which receives the fluid from the master cylinder and is pushed by it to press the brake pads located on either side of your disc (also called a rotor) up against the rotor, clamping down on it to slow its ability to turn, and this of course brings the car to a halt.

The problem you have, most likely, is that the highly polished sleeve inside your right front caliper in which the piston slides back a forth has become pitted with corrosion and gunked up with rust and debris that collected in the corroded area, and the piston is no longer able to slide smoothly and with ease. As a consequence, when it is pressed forward as you apply the brakes, it is no longer able to retreat when you let your foot off, and the brake pads remain in contact with the disc or rotor.

While the pads are designed to handle a certain amount of heat, being constantly in contact with the rotor produces far more heat and wear than they can handle, and so they wear out very quickly.

Offhand I would say, yes you need at least one new rotor, though you may not need one on the other side since it does not sound as if it failed. Otherwise the pads on that side would also have worn out very quickly. However, since pads are meant to be installed on both sides at the same time, and are sold in sets for that purpose, you might as well change the pads on both the right and left sides up front. But again, you may or may not need a new left caliper--that I would question.

Additionally, there was a reason the right caliper failed, and usually it is one of two things: either the rubber seal around the brake cylinder on the caliper got torn and admitted water and dirt to begin the corrosion process, or the brake fluid itself got so old that it had soaked up enough moisture to corrode the cylinder.

As a precaution, were it me, when I had the rest of the brake work done I would also have the brake fluid flushed and replaced to get the old fluid out of the system. Otherwise, you may be looking at similar failures on the other wheels in the not distant future.

Brake fluid, by its nature, has a capacity to absorb moisture. As you operate the brakes, and th piston goes in an out, it is not unusual for the piston to carry back in minute amounts of moisture into the fluid inside the calipers or wheel cylinders. Although miniscule (assuming the rubber seals are intact) this accumulates over time. Accordingly, it is a good idea every couple of years or so to flush the brake fluid to get rid of these impurities. (Incidentally, this is also why you do not use old brake fluid from half used containers to top off your system, as sitting around it can absorb humidity from the air.)

I hope this has been of some help. Should you have further questions, please feel free to contact me at [e-mail].

Answer 3

Whoever did the brakes last time either did not do them correctly and your front brakes were dragging or used cheap organic ones which only last about 10,000 miles. If you used the brakes after the pads were bad then you also destroyed the calipers.

Answer 4

caliper may have froze ...at 63000 new rotors are needed...also a brake fluid change is necessary...be certain to check the condition of the front wheel bearings when replacing the brakes .... reconditioned calipers are available at reasonalble prices. rebuilt calipers 2 at $65 each and rotors 2 at $65 each and pads at $60 and 1 + hrs labor at $90/hr. I estimate the job at $450 to 500. which is a complete rebuild.

Answer 5

While you may feel 10,000 miles is too short, think back, were you braking a lot more? Were you driving with your foot on the brake so you could brake faster? A lot of people do this in wet weather and its neither safer of cost effective, so get the caliphers replaced; you need all four working to stop safely.

Answer 6

Your caliper is bad. When you get the new ones put on, try not to brake fast. Ease on the brake farther back than usual. this will make them last longer because your car likes to burn through brakes.
