The piston is broken if it came out.
Remove the 4 bolts on the head, remove head and you will see the piston - be careful removing it because it is easy to score the cylinder walls if it is cockeyed.
Replace the driver, lubricate the O-ring before inserting

How do I replace a veneto flush piston in my toilet?


The piston sits inside the upper valve housing. The upper valve housing comes off by twisting the upper housing counter-clockwise. When you lift the valve housing out of the tank you will see the flush piston extruding from the bottom of the housing. The flush piston can be pulled out of the housing.. Yes, it just pulls out. And you just push the new piston in place.. Secure the valve assembly back into the tank by rotating the housing clock-wise.. Some Veneto toilets have two clips on the housing which secure the housing in place.

Hi I changed my gearbox on my 54 plate zafira 2.0 dti put a new slave cylinder in but it pop straight away do I need the fly wheel for that gearbox Many thanks john


If by pop you mean that the slave cylinder piston came out of the cylinder then I would fix that by installing a longer push rod to take up the extra length required by the slave cylinder being too far away from the clutch throw out lever (or relocate the cylinder closer to the arm. The length would be about 1/4" shorter than when the piston is fully bottomed out and that will give you a bit of free play and not let the clutch slip. Keep the fly wheel in mind but as long as the throw out bearing stays on the clutch input shaft housing then the flywheel would not solve much

How do you compress the break caliper on a 2004 Kia sorento


IS THIS A REAR OR FRONT CALIPER?
1. FRONT CALIPER: INSERT A LARGE C CLAMP WITH THE SCREW END INTO OPEN BORE OF CALIPER PISTON, THE STATIONARY END SHOULD BE SNUG AGAINST THE CALIPER END HOUSING: THAT THE PISTON MOVES IN AND OUT OF
COMPRESS C-CLAMP UNTIL CALIPER PISTON SEATS FULLY AGAINST THE CALIPER SEAL. INSTALL NEW PADS
2. REAR CALIPER: RENT AT AUTOZONE A REAR DISC CALIPER COMPRESSION TOOL. THESE CALIPER PISTONS WIND IN CLOCKWISE, INSTEAD OF JUST SLIDING BACK INTO A SMOOTH BORE. THEY HAVE GROOVES THAT FOLLOW A MATCHING SET IN THE CALIPER HOUSING.

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!!!

How do i change the brake pads?


REMOVAL AND INSTALLATION
  1. Remove disc brake caliper from mounting bracket and support with a length of wire or remove sleeve bolt and rotate caliper up and out of the way to remove shoes. Do not allow caliper to hang by the brake line unsupported.
  2. Remove outboard shoe and lining. Use a suitable tool to disengage shoe springs from holes in caliper housing.
  3. Remove inboard shoe and lining, unsnapping shoe spring from piston.
  4. If installing new shoe and linings, bottom piston in caliper bore using large pliers. Take care not to damage piston or piston boot.
  5. Remove bushings from mounting bolt holes in bracket. To install:
  6. Install new bushings to mounting bolt holes in bracket. Lubricate bushings with silicone grease before installation.
  7. Install inboard shoe and lining by snapping shoe retainer spring into piston. Shoe retainer spring is already staked to the inboard shoe. Shoe must lay flat against piston.
  8. Install outboard shoe and lining by snapping shoe springs into holes in caliper housing. Wear sensor should be at the trailing edge of shoe during forward wheel rotation. Back of shoe must lay flat against caliper.
  9. Install caliper.
  10. Apply approximately 175 lbs. (778 N) of force 3 times to brake pedal to seat linings.

Need to replace 1991 chevy astro van break pads and rotors and need a diagram


The following procedure requires the use of a C-clamp and slip-joint lock pliers.
  1. Siphon off about 2/3 of the brake fluid from the master cylinder reservoirs.

CAUTION The insertion of thicker replacement pads will push the piston back into its bore and will cause a full master cylinder reservoir to overflow, possibly causing paint damage. In addition to siphoning off fluid, it would be wise to keep the reservoir cover on during pad replacement.

  1. Raise and support the front of the vehicle on jackstands. Remove the wheels.
When replacing the pads on just one wheel, uneven braking will result; always replace the pads on both wheels.
  1. Install a C-clamp on the caliper so that the frame side of the clamp rests against the back of the caliper and so the screw end rests against the metal part (shoe) of the outboard pad.
  2. Tighten the clamp until the caliper moves enough to bottom the piston in its bore. Remove the clamp.
  3. Remove the 2 Allen head caliper mounting bolts enough to allow the caliper to be pulled off the disc.
  4. Remove the inboard pad and loosen the outboard pad. Place the caliper where it will not strain the brake hose; it would be best to wire it out of the way.
  5. Remove the pad support spring clip from the piston.
  6. Remove the 2 bolt ear sleeves and the 4 rubber bushings from the ears.
  7. Riveted style brake pads should be replaced when they are worn to within 1/32 in. (0.8mm) of the rivet heads; bonded style pads should be replaced when they are worn to no less than 1/32 in. (0.8mm) of the backing plate.
  8. Check the inside of the caliper for leakage and the condition of the piston dust boot.
To install:
  1. Lubricate the 2 new sleeves and 4 bushings with a silicone spray.
  2. Install the bushings in each caliper ear. Install the 2 sleeves in the 2 inboard ears.
  3. Install the pad support spring clip and the old pad into the center of the piston. You will then push this pad down to get the piston flat against the caliper. This part of the job is a hassle and requires an assistant. While the assistant holds the caliper and loosens the bleeder valve to relieve the pressure, obtain a medium pry bar and try to force the old pad inward, making the piston flush with the caliper surface. When it is flush, close the bleeder valve so that no air gets into the system.
Make sure that the wear sensor is facing toward the rear of the caliper.
  1. Place the outboard pad in the caliper with its top ears over the caliper ears and the bottom tab engaged in the caliper cutout.
  2. After both pads are installed, lift the caliper and place the bottom edge of the outboard pad on the outer edge of the disc to make sure that there is no clearance between the tab on the bottom of the shoes and the caliper abutment.
  3. Place the caliper over the disc, lining up the hole in the caliper ears with the hole in the mounting bracket. Make sure that the brake hose is not kinked.
  4. Start the caliper-to-mounting bracket bolts through the sleeves in the inboard caliper ears and through the mounting bracket, making sure that the ends of the bolts pass under the retaining ears of the inboard shoe.
  5. Push the mounting bolts through to engage the holes in the outboard shoes and the outboard caliper ears and then threading them into the mounting bracket.
  6. Torque the mounting bolts to 37 ft. lbs. (50 Nm). Pump the brake pedal to seat the linings against the rotors.
  7. Using a pair of slip-joint locking pliers, place them on the notch on the caliper housing, bend the caliper upper ears until no clearance exists between the shoe and the caliper housing.
  8. Install the wheels, lower the vehicle and refill the master cylinder reservoirs with brake fluid. Pump the brake pedal to make sure that it is firm. If it is not, bleed the brakes.

How do I retract the rear brake caliper piston


usually with a special tool you can borrow at autozone. because the rear brakes are usually the parking brake. you have to screw them back in. if there is a cross pattern or some type of groove in the piston will confirm this.
