I have to continuously replace calipers on my jeep, what is the problem?


wonder if the rotors are too slim. If this happens the brakes get too hot as the rotor radiates away the heat. If too hot the brakes could wear out faster.

My mechanic tells me I need rear brake pads and rotors as a cost of $ 320.00. I have 60000 miles on the car. I can't believe I need brakes so soon with low mileage.


The way in which a car has driven has a very direct impact on how long brake pads will last before they have to be replaced. For example, if you spend most of your time driving long distances on the highway, you're using your brakes much less often than in stop and go urban driving. I have seen cars that need brake jobs every 75,000 miles; I've seen similar cars, with different drivers and different driving routines, go 25,000 miles between brake jobs.

I would not be surprised at all if the front brake pads (and possibly rotors) of your Accord needed to be replaced at 60k miles of typical mixed driving. I am, however, somewhat surprised that your rear brakes need service at this point. The front brakes of a car typically provide much more of a car's stopping power than the rear brakes (it's a physics thing), and so they generally wear much more quickly than the rear brakes. All that said, I recently had to replace the rear brake pads and rotors of a 2002 Passat that had only 51,000 miles on the odometer. This car's pads were worn down to the metal, and one of the rotors was badly scored. Upon speaking with the owner of the car, though, things made slightly more sense. First, the car was equipped with a very active ABS braking system, which decreases front wheel braking and increases rear wheel braking depending on road conditions. As a result, the rear brakes of that car were used much more heavily than in the "average" car. Second, and more obviously, the owner admitted to forgetting to release her parking brake several times before driving off, sometimes going several miles before realizing her mistake. The emergency brake system on most cars engages the rear brakes, and driving off with those brakes still on will put a huge amount of wear on those pads in a very short distance.

One final, distant, thought is that it's possible that your rear calipers have gotten "sticky" and are not fully releasing after they have been engaged. Accumulated moisture on the brake pistons and piston channel walls can leave rust spots that hang up piston travel, leading to this condition. At the same time, it would be unusual for both brakes on the same axle to develop this problem at the same time--this typically happens one brake caliper at a time, and you notice the condition when you car begins pulling to one side when you brake or even after you release your brakes.

It only has 30,000 miles on it and the rear brakes squeal when applied when first driven cold. Does not do it after it has been driven and warmed up.


brakes typically only last about mas 30k miles. might be the brake lining warning shims letting you know its low or that plus glazed rotors/ drums needing to be replaced and or cut.

How to replace rear brake pads on 2002 buick rendevous


Those are special calipers. The piston cannot be just compressed back into the caliper - it needs to be turned as it is compressed or you can ruin the caliper.There is a kit you can rent from AutoZone or many independent auto parts stores that will perform both functions at the same time.
Block fron wheels and raise vehicle passenger side. Remove wheel. The caliper is on the top rear side of the assembly you're looking at.There are 2 long bolts you'll need to remove to take the caliper off the vehicle. Don't remove the brake line or open the bleeder screw ( either of these moves will add to your work!! ) Insert a large flat blade screwdriver in between the rotor and outboard brake pad and pry away from the vehicle slightly to release the pads from the rotor. Slide caliper upwards and towards the back of the vehicle to separate from rotor. The pads will come in a full set ( all 4 pads for both side of the rear ) . Look at your replacement pads and determine if they have a retainer clip holding them in place or a compression clip. Remove outboard pad first then inboard. Match old pads to replacement pads. Inspect rotor for grooves and irregular surfaces - if any grooves or irregularity present, remove rotor and take to an auto parts store for refinishing.Compress caliper piston with kit and allow 5 minutes for pressure to bleed back into the master cylinder.install rotor if removed and wipe surfaces with brake clean. Install inboard then outboard pad and place caliper on rotor, then mount to vehicle. Install wheel, repeat procedure for drivers side, then PUMP BRAKE PEDAL 5 TIMES BEFORE TRYING TO DRIVE VEHICLE to set pads on rotors.

I had the same problem with my 2007 kia optima. Replaced the pads at about 30k, The pads tend to get stuck and not fully release from the rotor. I took mine to the dealership at around 45k and they replaced the calipers and pads under warranty. According to the dealership the rear brakes are suppose to be serviced every 15k to prevent this from happening

nine times out of ten it's your brakes, but usually you would get a warning before it got that bad. i would remove the wheel and check the pads and the rotor. it the rotor feels like a 1977 vinyl record, then i would change or have the rotors turned

Recently had front & rear brakes replaced along with a new rear axle. Vehicle has 114,000 miles. The brakes shudder slightly with normal braking + some quivering of the steering wheel. With hard...


Its a good idea to turn your rotors if your putting on new pads so that you get a good seat.  The steering wheel vibration may be your new pads wearing in and trying to find a good seat.  Give it another 500 miles for break in period and if you still get the problem, then replace the pads with better ones and check to see if your rotors are not warped.  Your pads will never seat correctly if your rotors are warped and make sure you use plenty of that shim goop they give you in the package before putting on the pads.

How can i change the rear brakes pads?


1.Remove the cap from the brake fluid reservoir

2.Loosen the wheel nuts then raise the vehicle and remove wheel

3.Push the piston back into the bore to provide room for the new brake pads.A C-clamp can be used to accomplish this As the piston is depressed to the bottom of the caliper bore the fluid in the master cylinder will rise.Make sure is doesnt overflow.If necessary drain off some of the fluid. 4.Before removing anything,spray the disc,and brake pads with brake system cleaner dont use compressed air 5.remove the caliper mounting bolt,the banjo fitting for the brake hose shouldnt be disconnected unless you are removing the caliper or hose replacement

6.Swing the caliper up and secure the caliper up towards the spring with a piece of wire then remove the lower and upper anti-rattle springs.Remove the outer brake pad and shim then remove the inner brake pad ans shim(s)

7.Remove and inspect the upper and lower pad retainer clips,the pad retainer clips should fit snugly in the caliper mounting bracket;if they dont,replace them.Apply thin film of high-temperature grease to the retainer

8.Apply anti-squel compound to the back of pads install the new inner pad and shim(s) make sure the "ears" on the upper and lower ends of the pad are fully engaged with their respective grooves and the pad retainer clips

9.Install the new outer pad and shim if new pad has no shim take the old shimoff the old pad and install it on the new outer pad.Install the upper and lower anti-rattle springs

10.Clean off the caliper pin and coat it with high-temperature grease.Lubricate the lower caliper pin with grease too thenswing the caliper down over the disc and new pads (if the piston hits the inner pad depress the piston further into the caliper bore with your c-clamp

11.Install the mounting bolt and tighten it to the torque specifications (44-63) 99 and earlier models (51-55)00 and later models
12.Put the wheel back on and tighten lug nuts
