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.

Rear brake pads replace


Rent a tool from auto zone to help you compress the rear brake piston. It cannot be compressed with c clamp because the piston must be turned while it is compressed.
Autozone will charge you approx. $60 for the rental and then you get all your money back when you bring the tool back.
You need to compress the rear piston so you have room for the new, thicker pads.
The rest of the job is just like any other brake job. 1. remove one pin bolt and rotate caliper open to get to the pads. 2. compress the piston in with the tool 3. replace the pads. 4. assemble.

Change rear break pads on 2000 Buick. Cannot compress break cylinder in order to install new pads using C clamp and bleeding off break fluid.


There's a special tool required to compress the rear caliper pistons. You may want to rent the tool. If you look at the piston you'll see one or two notches. The special tool has nipples to fit these notches. The caliper piston will have to be compressed with the tool and the notches will have to be placed in the o'clock and 6 o'clock for the brake pads to slide over the rotor. If you rent the special tool have the renter show you how to use it.

Rear pisttons on ford 500 will not push in to install rear brake pads


If you have disk brakes, and you cannot fit the new brake pads in the callipers? Loosen the brake fluid reservoir cap to allow pressure to escape. Use a large C clamp connecting it to the front and back of the piston. Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads.

Can not get rear break piston to compress to allow for new pads


The rear disk brake piston does not compress back into the caliper, it has notces on the caliper piston that a tool fits into and the caliper piston is actually turned or screwed back into the caliper, and a notch in the piston must also be aligned to fit the the small protrusion from the backing plate of the inner brake pad.

The brake tool can be obtained from most auto part stores, and it is usually square with protrusions sticking out from the sides in different patterns to fit various caliper pistons, and it usually attaches to a 3/8" drive extension and ratchet.

Do not compress this type of caliper piston because the caliper can damaged.

I cant seem to get the rear brake caliper to compress so it will fit over the new pads


There are two stlyes of calipers for the rears. One is ratcheting so the piston has to be turned back to colaspe. The other type compresses with a C clamp. If a large retaining spring is on the inner part of the caliper you have the ratcheting type. A brake cable will attach to the spring as well. If not it will compress instead

Compress rear brake caliper on 1996 nissan maxima


Compressing Rear CalipersIf you open the "bleeder valve" you'll need to bleed the air from your break system. As your breaks wear down, the level in yor break resivor will drop. what works for me is the following: Remove the cap on your resivor and place some shop raggs around the base. With a large "C" clamp push the piston back/into the break caliper (slowly) when the piston is all the in your resivor level will come up. When you complete both sides, you resivor should be near the corect level. Remember that when you put it all back together, your break pedal will go to the floor. Do this a few of times and your break pedal will tighen up. Now you should check the level in the resivor.

Hope this helps and be safe.....

Are any special tools required or any special process to change the rear brake pads on a 2006 Jetta? I have changed pads on BMW's Fords Chevys etc....but you never know, so I thought I'd ask. thanks!


These cars usually have disk brakes in the back. You need a caliper piston rotator tool, this tool fits into the caliper piston and you must turn it in to retract the piston, it fits onto a 3/8 " drive socket wrench. Npa sell a universal one for like $15.00 - $20.00.
