How can i compress the caliper piston back of audi a6 2000 2.8l awd what kind of tools i need . Vise grip is not working.


For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also.
But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!!

For front brake pads. You should buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!!

Check brake fluid level and top up if neccessary!!!

Brake Caliper - Removal & Installation

CAUTION Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.
Inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
  1. Raise the vehicle and suitably support.
  2. Remove the tire and wheel assembly.
  3. Pull down on the front park brake cable.
  4. Remove the front park brake cable from the park brake cable connector.
    NOTE When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 1 mm (0.039 in.) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism.
  5. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad. Compress the brake caliper piston into brake caliper bore to allow the piston enough clearance to slide the brake caliper off the brake rotor.
  6. Remove the C-clamp.
    NOTE Be sure to plug the opening in the brake caliper and brake hose to prevent fluid loss and/or contamination.
  7. Remove brake hose to caliper bolt attaching the brake hose to the brake caliper.
  8. Remove the brake hose from the brake caliper.
  9. Remove and discard the two copper brake hose gaskets. These gaskets may be stuck to the brake caliper and/or the brake hose end.
  10. Remove the park brake cable bracket from the brake caliper. Leave the park brake cable attached to the cable bracket.
  11. Disconnect the park brake cable from the park brake lever on the brake caliper.
  12. Remove the lower brake caliper pin bolt.
  13. Rotate the brake caliper up.
  14. Remove the brake caliper from the upper brake caliper pin bolt.
To install:
  1. If reusing the brake caliper retainers, clean the sleeves using denatured alcohol, or equivalent.
  2. Lubricate the brake caliper pin bolts with a thin coat of high temperature silicone lube.
  3. Install the brake caliper to the upper caliper pin bolt.
  4. Rotate the brake caliper down over the brake pads into the brake caliper bracket.
  5. Install the brake caliper pin bolts. Tighten the brake caliper pin bolts to 27 Nm (20 ft. lbs.).
  6. Remove the plugs in the brake hose end.
    NOTE Install NEW copper brake hose gaskets.
  7. Assemble the brake hose bolt and the NEW copper brake hose gaskets to the brake hose.

How do u change front brakes on a 2004 kia optima


1. Park on a flat and level surface. Apply the parking brake. Secure the vehicle by wedging something behind the wheels to prevent the vehicle from rolling.
2. Use a syringe, turkey baster or similar tool to siphon out the brake fluid from the master cylinder reservoir until it's approximately one third full. You can't reuse the old fluid, so you'll need to dispose of it.
3. Remove the wheel and the caliper guide pin bolts. Lift the caliper away from the rotor. Suspend the caliper from the frame using mechanics wire. Remove the brake pads and retainer spring from the caliper. Compress the caliper piston into the bore.
4. Reinstall the brake pads. Place an anti-squeak product on the outside of the brake pads, making sure not to get any of this on the inside of the brake pads. Reinstall the retainer spring to the caliper. Reinstall the caliper in position on the caliper support bracket. Reinstall the guide pin bolts. Reinstall the wheels.
5. Add brake fluid. Start the engine and pump the brakes 3 to 4 times.test drive at slow to moderate speeds to ensure worked correctly.

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

Does the rear caliper piston need to rotate as it is compressed?


No you do not.

Here is the steps for the brake job and it does not state that other than compressing the piston, you do NOT have to rotate it like on some foreign vehicles:


Removal & Installation
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Drain2/3of the brake fluid from the front reservoir. Use the bleeder screw at the front outlet port to drain the fluid. If equipped with anti-lock brakes, relieve the system pressure.
  3. Raise and safely support the vehicle.
  4. Remove the wheels.
  5. Pry the caliper support spring out of the caliper.
  6. Remove both caliper slide pin bushing caps and slide pins.
  7. Lift the caliper from the anchor.
  8. Using a piece of mechanics wire, support the caliper so there is not tension on the brake hose.
  9. Remove the brake pads from the caliper.

Rear brake pads—Liberty


To install:
  1. Position the brake pads onto the caliper.
  2. Position the caliper into place on the anchor.
  3. Coat the caliper slide pins with silicone grease and torque them to 18 ft. lbs. (25 Nm). Install the slide pin bushing caps.
  4. Install the caliper support spring in the top of the caliper under the anchor; then, install the other end into the lower caliper hole.
    NOTE Hold the spring in the caliper hole with your thumb while prying the spring end out and under the anchor.

  5. Fill the master cylinder with fluid and bleed the brake system.
  6. Before driving the vehicle, pump the brakes several times to seat the pads.
  7. Install the wheels.

Reinstall rear brake caliper on 2007 Jetta


If you look at the piston on the Caliper it has 2 grooves on the face where the Brake pad mates to it. There is a special tool to push and turn the piston back into the caliper bore. that type caliper is also used to apply the parking brake. cable attached to rear of caliper and to an arm with a heavy spring. If you go to Harbor freight they have an inexpensive set for this.

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.

Worn brake pads


Front brake pad exchange guide.

Step1 Park the Dodge Durango on a flat surface. Put the emergency brake on and put wedges behind the wheels to prevent the vehicle from rolling. Disconnect the negative battery cable from the battery. Drain 2/3 of the brake fluid from the master cylinder, using a syringe. Remove the wheel and the tire assemblies. Step2 Compress the caliper piston back into the caliper bore using a large C-clamp to drive the piston into the bore. Use additional force if it is required. Using a 3/8 inch hex wrench or socket remove the caliper mounting bolts. Step3 Rotate the caliper rearward off the rotor and out from its mount. Remove the inboard and outboard brake pads. Remove the spring clip that holds the inboard brakes in the caliper. Tilt the pad out at the top to unseat the clip. Remove the retaining spring that secures it in the caliper. Unseat one spring end and rotate the pad out of the caliper. Step4 Suspend the caliper assembly from the Durango frame using mechanic's wire. Do not allow the caliper assembly to dangle from the brake hose as this may damage the brake hose. Step5 Clean the surfaces of the caliper and steering knuckle with a wire brush. Apply multi-mileage grease or similar product. Using brake fluid or break cleaner clean the caliper slide pins. Apply a light coating of silicone grease to the pins. Step6 Install the inboard brake pad and it's spring. Install the outboard brake pad. Install the caliper over the rotor and seat it in its original position until it is flush. Using a torque wrench, torque the slide caliper pins to 22 ft./lbs. Step7 Add brake fluid to the master cylinder. Bleed the brakes. Reconnect the negative battery cable to the battery. Start the engine and pump the brakes 3-4 times to seat the brake pads. Reinstall the wheels. Test drive the Durango at slow to moderate speeds to ensure that the maintenance was performed correctly.
Rear brake pad exchange.

Step1 Lift the Durango off the ground with a car jack. Support the vehicle on all sides with jack stands. Keep children and small animals out of the vicinity when you replace the brakes. Step2 Loosen the lug nuts on the wheels with a torque wrench. Remove the wheel and tire assemblies and set them aside, face up, to prevent damage. Step3 Compress the caliper and remove it by lifting the top up and off the caliper adapter. Hang the caliper from the Durango's frame with mechanical wire. Step4 Remove the inboard and outboard brake shoes from the caliper adapter. Take off the top and bottom anti-rattle springs. Keep the springs separated, as they aren't interchangeable. Step5 Press the piston into the bore with a C-clamp. To prevent damage to the pistons, insert an old brake shoe in between the C-clamp and caliper piston. Remove the C-clamp. Step6 Wipe down the caliper mounting adapter and anti-rattle springs with brake cleaner. Grease the anti-rattle springs with brake grease. Install the bottom anti-rattle springs, followed by the top anti-rattle springs. Step7 Install the inboard brake shoes followed by the outboard brake shoes. Replace the caliper and the wheel and tire assemblies. Lower the vehicle to the ground and pump the brakes to seat the pistons.
