Unfortunately, the lip seal which your caliper piston rides on is leaking. The only remedy for this problem is to replace the caliper.

1999 Yamaha Kodiak Front Disc Brake - Rebuilt master cylinder with new parts. Replaced orings on piston in front caliper and bleed brakes using new fluid. The piston will not retract. What is proble


The brake hose is clogged. When under pressure from applying breaks, the piston is forced tight to the rotor. When released the fluid will not return through the hose because there is no real pressure. Replace the hose.

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!!!

    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.

    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.
