Try a C clamp. Don't forget to put a rag around the brake fluid reservoir, since you will be forcing fluid back into it, likely causing it to spill over.

Sounds like the accumulator ball on the side of the master cylinder. I don't know how to check it,but what ever you do just don't unscrew it with out knowing what you are doing they have to have the pressure taken out of them by pressing the brakes at least 10 times with the engine off. That thing will take off like a rocket if you don't. Or the simple thing is air in the lines start bleeding from the furthest tire to closest.

Need to replace the front & rear brakes . Is there any special tools needed to do this job .


For caliper brakes, mainly a large C-clamp or brake cylinder piston tool, to collapes the piston back into the caliper, to install the new pads. If you have rear drum brakes, they make a couple different brake spring tools for removing the springs on the brake shoes.

How do i release the brake caliper pistons to be able to fit new brake pads on a renault trafic 08 van. thank you


Renault trafic brake calipers on the front can be pushed in with a G-clamp, but rear calipers need to be wound in, if you look at the piston it has notches for a winding tool!

Rear brake piston compression problem? How do I compress the rear piston into the caliper to allow new brake pads to be installed?


As far as I know, most front disc brake setups have pistons that are pressed back into the cylinders using a C-clamp or something similar.

However, not all rear disc systems are like this. There are some that require that the rear pistons be screwed back into the cylinder bores. These pinstons usually have some kind of indentations on the front where special tools fit and help move them back into the cylinder.

Your Hyundai may have this kind of setup.

2006 mercury mailn rear breakpad replacment.I can't compress the breakcillender piston so that the calaper will acept the new pads


Greetings Milan Owner:
You need a C clamp you can pick up any auto parts store or hardware store and must position it to the front center of the piston with piece of wood accross the front piston and rear center of the caliper and turn the screw by its handle until the rubber part of the piston receeds even with caliper. Once even with the caliper you can put the pads on and slide the caliper on to the rotor. You can also carefully with the right wrench or socket open up the valve on the caliper and let some brake fluid out (very little). This will make it easier for the piston to receed into the caliper with a little help from you using a piece of wood to push it in. Using the second option you will definitely have to bleed your brakes to get a hard brake pedal in the car. Do not forget to add more fluid back to the master cylinder. Good Luck[

1999 honda accord ex v6


The back brakes on my Honda Accord are disc brakes. After removing the brake cylinder assembly you will see the brake cylinder piston end has a slot in it. The short pin on the back side of the inner brake pad fits into this slot, but also it is used to 'Turn' (clock-wise) the piston back into the cylinder so you fit the assembly back over the new 'thicker' pads. You can not 'press' this piston back into the cylinder.

Rear brake to remove replace disk and service due binding


Preliminaries Do 1 wheel at a time Use a jackstand on the wheel you are working on (safety First) Remove the tire on the selected wheel
The Brake caliper is usually held on by 2 bolts. Some of the bolts are Allen wrench type, usually about ¼ inch or 5/16 inch. Remove and the complete brake caliper can be lifted off the rotor. The pads can now be removed. Before installing the new pads you must first return the pad piston to their original position in the caliper. Open the hood of the engine compartment and remove the cover on the master cylinder. This allow the brake fluid to be returned to the master cylinder. To return the pad piston to the original position you will need a C clamp and a flat piece of metal like a small flat file. Put the flat piece of metal on the piston and use the C clamp to put pressure on the piston. Tighten the C clamp slowly and you will see the piston slowly retract into the caliper body. Now you can insert the new pads into the caliper. Mount the caliper over the rotor and reinstall the 2 bolts.

Loringh Hope this helps Good Luck PS Please leave a rating if Appropriate Thanks
