Hi! I need to compress the rear brake calipers to change the brake pads. Do I need a special tool? I tried a C clamp. No luck there.

Dear Sir/madam,

The pistons on the rear brake calipers SCREW in to the caliper. There are notches on the inner edge of the piston face. engage the notches with a large needle nose plier or a large flat washer and turn clockwise (as you face the piston) to turn the piston in.
There is a special tool that is available at your local autoparts store that is absolutely necessary and will save you a ton of time and aggravation. Using a needle nose plier or washer does not allow you to apply enough pressure unless your are the incredible hulk.

thanks
Good luck

HOW DO I CHANGE THE BRAKES REAR ON 2008 TAURUS. I


Hi, if you are replacing the rear pads, you will need a special caliper tool(can be purchased or rented from Autozone or Discount Auto Parts) to reseat the piston as it has to be turned or rotated inward to reseat..

To move the piston back into the caliper, the LH piston is turned clockwise and the RH piston is turned counterclockwise. NOTE: A moderate to heavy force toward the caliper piston must be applied. If sufficient force is not applied, the internal park brake mechanism clutch cone will not engage and the piston will not compress. Using the special tool (or equivalent such as OTC tool 7317A), compress the brake caliper piston into its cylinder.



In an emergency, you can use needle nose pliers, but be careful not to pinch the rubber boot or seal as this will create a leak of brake fluid....

Steps to replacing rear brake pads


A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

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.

Compressing the rear disc brake caliper on 2008 grand caravan


The rear calipers on these models require a special tool that compresses and turns the piston in at the same time -- most parts stores carry this tool.

It is called a caliper piston press -- and it installs where the pads would go and acts like a c-clamp,when turning handle it will turn the caliper piston backinto the caliper as it compresses it.
Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the Parking Brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor,MILLER Special Tool 8807, . Any other seating method will damage the self-adjuster mechanism.
Good luck and hope this helps.

When trying to change the rear pads on a 2005 Montana SV6 I was not able to compress the caliper. It appears as if they need to have the pressure relieved from the system. Do I need to just apply more...


No, on rear wheel disc brakes, the pistons have to be turned in clockwise, and you need a special tool to do it, or you have something strong enough to put in the slots and turn it, but just turn them in far enough to get the new pads to slide over the rotors.

1996 olds aurora back brake pad replacement, how to compress the pads to get the caliper back over the pads?


Special tool is a 1" cube with tabs on each side that fits into indentations on the brake piston and can be purchased for $10-12 @ most discount parts stores. Use 3/8" ratchet with short extension and 'special tool to carefully turn piston onto internal hand brake screw. Take care to not tear dust boot. When piston is fully collapsed, make sure to align piston indentations perpendicular to brake pad as there are bumps on pad that fit into them. Also while screwing in piston either remove about 2/3 of brake fluid in master cylinder and refil afterwords or open the bleeder valve on brake piston assembly. Bleed if necessary.

I am replacing the rear pads and cannot get the caliper to compress using a c-clamp. Is there something special I need to do or know on my montego 05 car to get the caliper to compress? Sincerely Desperate...


One, take your brake fluid reservoir cap off.
Two, use a thin piece of wood to help you compress the piston on the caliper....do it slow. This way, you don't create a lot of pressure to the reservoir and it won't overflow.
Three, these are the steps to removing and replacing the pads for the rear. It does mention a special tool....but you can use a c-clamp for the same purpose:

Rear To Remove:
  1. Check the brake fluid level in the brake master cylinder reservoir.
  2. If required, remove the fluid until the brake master cylinder reservoir is half full. CAUTION
    Care must be taken when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever.
  3. Remove the disc brake caliper. Support the caliper with mechanic's wire. CAUTION
    When the brake pads are separated from the brake caliper, new brake pads must be installed. The brake pads are one-time use only.
  4. Remove and discard the brake pads and spring clips from the brake caliper anchor plate. NOTE: Do not remove the anchor plate guide pins. The guide pins are press fit to the brake caliper anchor plate. If the guide pins are damaged a new anchor plate must be installed.
  5. Inspect the brake caliper anchor plate assembly.
  6. Check the guide pins and boots for binding or damage.
  7. Install a new brake caliper anchor plate if it is worn or damaged.
To Install:
NOTE: The left caliper piston turns clockwise and the right caliper piston turns counterclockwise.
  1. Using the special tool, turn and compress the brake caliper piston into the cylinder.
  2. Clean the residual adhesive from the brake caliper fingers and pistons using the specified brake parts cleaner. CAUTION
    Do not allow grease, oil, brake fluid or other contaminants to contact the brake pad or caliper mating surface. Do not install contaminated pads.
    NOTE: Install all the new hardware supplied with brake pad kit.
  3. Install the new spring clips and brake pads.
  4. Position the brake caliper and install the 2 bolts. Tighten caliper bolts to 23 ft-lbs (31 Nm).
  5. If necessary, fill the brake master cylinder reservoir with clean brake fluid.
  6. With the engine running, apply pressure on the brake pedal to seat the brake pads.
  7. Test the brakes for normal operation.

My VW 1.9 Passat diesel y reg rear brake pads need changing, Is this an easy job for an average DIY man? Do I need special tools and anythiing to be aware of.


Yes you will need special tools for a rear brake job. you will need a set of xzn wrenches large ones say 12 and up to 18 I believe, and you will need a caliper tool that spins and compresses the caliper at the same time
