How to collapse rear calipers on 2005 free star ford


Open bleed valve,use a piston tool, to
turn parking brake in,as you push piston
back into caliper

The piston should screw in clockwise
That is the parking brake feature
The piston also has to be retracted ,as on the front

After the pads are on, ratchet up the P-Brake
to tighten pad clearance

You don't need to open bleeder, but it is easier,
and you absolutely have to flush brake fluid on ALL
vehicles every 2 years

2006 malibu maxx - the rear brake caliper will not depress.


If you are replacing the rear pads and are trying to retract the caliper pistons here is what you need to do.
Use a piston installation tool in order to twist the brake caliper piston into the brake caliper bore.
If you do not have the tool you can retract the piston by using a needle nose plier.
Exert downward force and rotate clockwise until the piston bottoms out.
Before installing be sure the two "U" shaped slots are at 6:00 and 12:00 Oclock.

2003 mazda protege 5,changing brake pads caliper piston will not go back


you will need to remove the brake line from the caliper, if the caliper will go back then you could possibly have a bad brake line. Also, you should open the reservoir when pushing the caliper back to allow the pressure to release. If the caliper does not go back, then you will need to either rebuild or replace the caliper.

Rear brake pad installation 99 volkswagen passat


If you can't see diagrams(sometimes happens) let me know and I will get them to you

  1. Raise and support the vehicle. Remove the rear wheels.
  2. If equipped, disconnect the brake pad wear sensor from the harness.
  3. Counterhold the lower sliding pin using a thin open-end wrench and remove the caliper-to-sliding pin hex bolt.
  4. Pivot the caliper upward or if necessary remove the upper caliper-to-sliding pin hex bolt.
  5. Using a brake caliper retraction tool, select the appropriate sized piston press arbor and install the tool onto the brake caliper. Following the tool manufacturer's recommendations, use the tool to rotate the caliper piston clockwise as it is pressed into the brake caliper housing, until it is fully retracted.

  1. Clean the brake caliper and all sliding surfaces. With the caliper piston pressed fully back into the caliper housing, check for leaking fluid and damaged dust boots.
  2. If equipped, install a new brake pad wear sensor in the pad if the plastic part has been worn through on the old sensor. New sensors are not required unless the wire inside the plastic part has been exposed.
  3. Lubricate the slider bolts with approved brake grease.
  4. Install the brake pads onto the bracket assembly, and then carefully lower the caliper over the caliper mount. Check and make sure that the pad springs are correctly seated.
  5. Replace all removed caliper-to-sliding pin bolts and torque to:
  6. 1990-97 Passat models: 25 ft. lbs. (35 Nm)
  7. 1998-00 Passat models: 22 ft. lbs. (30 Nm)
  8. If equipped, connect the brake wear sensor wire to the harness. Check for a good connection as most problems with the sensor circuit are caused by faulty connections. Check that the wire is held by the loop in the dust cover and the connector is held at the clips.
  9. Install the wheels and hand tighten the lug bolts. Lower the vehicle carefully until the tires begin to contact the surface and torque the lug bolts to specification in a crisscross pattern to:
  10. M12 x 1.5 lug bolts: 81 ft. lbs. (110 Nm)
  11. M14 x 1.5 lug bolts: 89 ft. lbs. (120 Nm)
Feel free to contact if you have any questions

Brakes


If its the front brakes you are working on and the piston won't retract into the caliper then you need a new caliper, or both actually. Calipers need to be replaced in pairs. If you are working on the rear then you need a special tool to turn the piston back into the caliper. you can get the rear disc brake tool at any auto parts store. Turn the piston clockwise to retract it, and pay attention to the little spots cut out of the piston that the tool grabs to turn it. They need to be at the top and bottom of the piston once you fully retract it or the little pin at the bottom of the inside brake pad wont sit against the piston. And once again if it still wont retract then you need to replace both calipers. Once you are finished you need to pump up the brake pedal and then pull up the parking brake lever and release it 10 to 20 times to adjust the piston.
