Us a large " C " clamp and place one end on the back side of the caliper and the other end on the piston side ( place the old brake pad over the hollow part of the piston hole ) nd slowly tighten the " C " clamp. you will need to do this slowly as I say or the brake fluid will squirt out of the top of the master cylinder.
Good luck and I hope that this helps you.

Sticking brakes


Hi,if you are talking about the front calipers,I serjest you buy some brake cleaning fluid,first open the bonnet and undoe the cape from the brake resiver and put a absobent rage around the top so you dont get brake fluid over eneything, take road wheele off,then spray the pistons that push the brake pads on to the brake disk (rotor)then get a screwdriver and pu between the pads and the brake disc and gently lever the brake pads away from the brake disc untill the piston is neerly in the brake caliper,then go inside the car and apply the brake then check level of fluid in resiver if ok go back to wheele caliper and repeat about free times (on bothe sides. that should cleer the dirt thats cousing the pistons to stick.(make shore that the rubbers on the calipers are not damidged if so you should replace them)hope this was some help.

How to replace AUDI front brake disc


Atention!!!
Don't disconnect any brake line from caliper!
Don't disconnect any ABS 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. Remove brake carrier from wheel bearing housing (two ribbed bolts). 125 Nm 7. Remove brake disc from wheel hub. 8. Install brake carrier on wheel bearing housing. Tightening torque for two ribbed bolts = 125 Nm. 9. Check up the brake fluid level on the reservor, and emptying if neccessary! 10. Push piston back into brake caliper housing. 11. 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). 12. Install outer brake pad into brake carrier. 13. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 14. Install both caps. 15. 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!!!

If the brake caliper piston will not go back into the piston bore do it need to be replaced.


try to get it overhauled..because might be it has gone jammed due to dust clottings......else get it replaced due to severe risks of brakes jams

I cant get the brake disc to push back in to replace the brake pads. Is there a switch in the Master Resevoir that I have to open and if so how?


No, see procedure below listed at autozone.com. Try opening bleeder. You may have a kink somewhere or hose decomposing internally. Else the piston is locked in place. Was the brake working before replacing pads?

  1. Remove 1 / 2 of the volume of brake fluid from the master cylinder to prevent overflow when the caliper piston is compressed.
  2. Raise and safely support the vehicle.
  3. Remove the wheel and tire assemblies.
  4. Remove the brake caliper without disconnecting the brake line. Support the caliper with a length of wire. Do not let the caliper hang from the brake hose.
    NOTE On some disc brake systems it is not necessary to remove the caliper when installing new brake pads. Remove the lower slide bolt and rotate the caliper upward to remove the pads.
  5. Remove the brake pads and shims. Inspect the brake rotor and machine or replace as necessary. Check the minimum thickness (specification is cast into the rotor) before machining.

To install:
  1. Use a suitable tool to push the caliper piston into its bore.
  2. Apply a thin coat of grease to the rear face of the brake pad and install the shim. Install the brake pads.
  3. Install the calipers. Lubricate the caliper bolts and boots. If equipped with a 4-cylinder engine, tighten the caliper mounting bolts to 24 ft. lbs. (33 Nm). If equipped with a 6-cylinder engine, tighten the caliper mounting bolts to 54 ft. lbs. (74 Nm).
  4. Install the wheel and tire assemblies and lower the vehicle.
  5. Apply the brakes several times to seat the pads before moving the vehicle. Check the fluid in the master cylinder and add as necessary.

Removal and replacement of brake shoes 1999/2000 on ford escort e


Hi
Firstly put the hand brake on and loosen the wheel nuts, jack the car and remove the wheel, if you turn the wheels out so you have a better view. then remove the 2 10mm bolts from the rear of the brake caliper, there will be a hard tough wire coming over then brake caliper pop this off with a screw driver or pliers. now open the bonnet and remove the cap from the brake fluid bottle. once done leave it off and then retun to the brakes, get a flat screw driver and place it between the inner most brake pad and the brake disc then push the 2 apart, once these have been moved lift the caliper off and the brake pads should come free. the caliper has a cylider/ round part that pushes the pads against the disc ensure that the cylider is pushed right back into the caliper using some big grips large pliers. once the cylinder is right back you should be able to fit the new pads. replace all the parts in reverse order, but before putting the wheel back on push the brake pedal several times until the pedal feels hard. then replace the wheel and do the other side. once complete check the fluid level on the brake fluid and replace the cap.

This is a fairly easy job should take a novice about 40mins a side but if your quite savvy with cars then you can complete the whole job in about an hour.

Hope this helps if not please get back to me so I can be more accurate, and talk you through it.

Regards
Dan

I am unable to push the brake accuator back to its "back" position in order to reattach the calipers with new brake pads in them


Try to use a large C clamp with one of the old pads on the caliper piston and the other end on the back side of the caliper body, and turn the clamp in to push the piston back. make sure the brake flex line is not pinched or kinked as it will not allow the fluid to flow back to the brake resovoir. The caliper may also be seized if these things dont work, then it will have to be replaced. Take it to a garage, since the brakes will have to be bleed after replacing the calipers, (If you replace one side recommend replacing the other side)

Installing front brake pads


    • Some of the fluid from the master cylinder
    • Wheels
    • 2 caliper guide pin bolts
    • Caliper assembly by swinging the top part of the caliper away from the brake rotor edge, then lift the caliper assembly up
    • Outboard brake pad by prying the brake pad retaining clip over raised area on the caliper. Then slide the pad down and off the caliper.
  1. Before removing the inboard brake pad, use a large C-clamp to press the piston back into the caliper. This will prevent possible damage to the caliper piston. It is good practice to remove some (1/3–1/2) of the brake fluid from the reservoir. This is because as the caliper piston is pushed back into the caliper, brake fluid will be pushed back through the lines, back into the master cylinder and fluid reservoir, possibly causing the reservoir to overflow.
    • Inboard brake pad by pulling away from piston until the retainer clip is free from the cavity in the piston. 0900c152802197b8.jpgRemoval and installation of the disc brake pads
To install:
  1. Lubricate both the caliper mating surface and the machined abutment surfaces with multi-purpose lubricant.
  2. Before brake pad installation, be sure to lightly coat the outer backing plate surface of the new brake pads with a disc brake pad anti-squeal lubricant, usually a gel-like material that deadens any high-frequency vibration that can be the source of disc brake squeal.
  3. Install or connect the following:
    • Brake pads into the caliper assembly making sure both pads are seated securely onto the caliper
    • Caliper assembly back into position over the brake rotor
    • Caliper guide pin bolts and torque to 17 ft. lbs. (23 Nm)
    • Wheels and lug nuts. Torque the lug nuts, in a star pattern sequence, to 100 ft. lbs. (135 Nm).
  4. Top off the master cylinder to the appropriate level, using DOT 3 type brake fluid only.
  5. Before moving the vehicle, pump the brakes until a firm pedal is obtained. Road test the vehicle to make sure the brake operation is normal.
