To depress a brake piston without a tool, you can use a large C-clamp or a similar object to gently push the piston back into the brake caliper. Place a piece of wood or a thick cloth between the clamp and the piston to protect it from damage. Slowly tighten the clamp, ensuring even pressure, until the piston is fully retracted. Always check the fluid level in the brake reservoir as you do this, as it may rise and overflow.
it can be done with a C clamp and a block of wood. ( to prevent burring piston edges.) remember to loosen the brake fluid reservoir top first.
Buy or rent the tool that is required to screw the piston into the caliper. Germanautoparts.com sells them. FLAPS (checker, schucks, kragen) may have them to rent.
You have to use a special tool to turn the piston in clockwise. The tool has two pins which match the two recess holes on the piston. Since the caliper is also the emergency brake you cannot just c clamp the piston back into the caliper bore. you should be able to rent the tool at your local autozone or autoparts store.
The piston retracts by turning it back in. You will need a Disc Brake Pad Spreader (Part Number: 648412) and a Disc Brake Piston Tool (Part Number: 648410) found at Advance Auto Parts. The Brake Piston Tool looks like a Rubik cube. Simply line up the knobs into the piston slots and place the disc brake pad spreader between the caliper and brake piston tool. Apply slight pressure on the piston via the pad spreader and turn the brake piston tool with a screw driver while continuing to apply pressure on the brake piston tool. From what I have read they could retracted by turning either clockwise or counterclockwise.
If the parking brake is connected to the caliper then the piston is threaded and a special tool (not expensive) is required to spin the piston in to the caliper body. Tool is available at Sears or auto parts If parking brake not connected-you should be able to compress piston with a "C" clamp As well if you are referring to the rear pads of course, you can get a pair of needle nose pliers, put 1 end in each groove, and rotate clock-wise to depress the piston, there is always a way around "special" tools, good luck to you
First make sure the parking brake is OFF, then remove the caliper and use a C-clamp to SLOWLY depress the piston until it is flush with the caliper surface. Second, on some vehicles however you may need a special tool to turn the piston to depress it. Third, consult a repair manual as the procedure may be different still.
Brake piston? Front use a "C" clamp to compress Rear - Piston is threaded turn clockwise to compress (water pump pliers?)
A disc brake piston tool is the best tool to use for removing brake pads on a car. It helps compress the piston back into the caliper, making it easier to install new brake pads.
On some vehicles there is a special tool required. The piston is pressed and turned at the same time. Of course you must remove the master cylinder cap, in order to be able to push it back on any car. If it has a criss cross patteren on the face of the piston, then you need this tool. Some Suto Parts stores will lend you the tool, if you buy the parts from them.
A brake rotor removal tool that is commonly recommended for replacing brake rotors on a car is a brake caliper piston compressor tool. This tool helps compress the caliper piston, making it easier to remove the brake rotor. It is important to ensure that the tool is compatible with your specific car model before using it.
A c-clamp will work just fine. If it takes a lot of pressure to retract the piston the caliper may need replacement or rebuilding.
no but to depress calipers because of parking brake setup screw piston cup in. c clamp will only break the calipers
