HI,
Usually one would use a "C" clamp to squeeze the piston flush with the caliper for the clearance needed. If you do not have access to a "C" clamp you can use the old brake pad as a cushion and pry with a crow bar or a large screw driver, the piston backwards for clearance. Try and pry evenly as not to **** the piston in the caliper.
I hope this may have helped you.

You need to turn the piston while pressing the piston. There are tools made for this.

This one might work but usually will not

This one is the one you want. Works every time because it can hold pressure on the piston better while it rotates the piston.

Change brake pads


For starters the front and rear us disk pads and it is not hard to do. On the front jack up the front and us jack stand for safety. After you take of the wheel remove the two bolts at the back of the brake caliper remove the caliper and then the old pads us a C- clamp with one of the old pads installed in the caliper then just us the c-clamp to push the cylinder all the way in until it will go no further install new pads put back on. But before you do the next side hit the brake to push the cylinder back out. Go to other side do the same thing. On a side not you only need to replace the rear brakes every other time you do the front. The front wear twice as fast as they do most of the stopping.

Chang rear brake pads ford focus 2008


I can help you with this problem step by step remove the wheel one at a time. after removing wheel look behind the rotor for a 8 or 10 mm bolt or an allen head screw remove both of these. Then pry the brake housing up and off of the rotor once off look at both pads the one near the round cylinder may be different than the one in front make sure you look at both pads where they are while removing them. Once removed the rear pad where the cylinder is behind it needs to be pushed all the way in flush with the rubber carefully not tearing the rubber around it. Reinstall your pads in the same location they were in put the caliper back over the rotor there will be little room between the pads for this you may have to push hard. Once on put the 2 bolts back it tightly not over tight they do break. put back on your tire let it down then go inside and pump the brake pedal 2 to 4 times until hard then do the other tire. one at a time and look for anything left on the ground when done there should be only 2 bad pads nothing else. if you need further assistance during the procedure. my email is sj196653@yahoo.com request chat mention brakes in subject we will go from there.

Hi i own a 1998 chevy siliverado and my brakes are not working adequately, im not losing break fluid so im unsure of the problem


If the pedal seems really hard to push, you could have a bad brake booster. If the pedal feels OK but there is not much action from the brakes, there could be an internal leak in your master cylinder. If your vehicle is equipped with Antilock Brakes, it could be a bad Hydraulic Control Unit.

Break loose your Lug Nuts Jack it Up Secure the Car with Good Jack Stands.Then finish remove tires,Besure To take the cap off your Masrer Cylinder and Take a Suction Bulb and Remove not Quite 1/2 of the Brake Fluid out of the Master So when you Push the Pistons Back in the Caliper you don't Get Brake Fluid Everywhere. Know you'll see your Calipers and Brake Pads. Remove Calipers.NOTE: Check your Calipers for Corrosion that Builds up over the Years on the Caliper piston.

I would Just Replace both Rear Rotors.Also while you have the Wheels Off, Inspect your Rear Bearings.If the are not showing Wear then Clen Them and Re-Pack with a Heavy Duty Wheel Bearing Grease & New Cotter Pins. NOTE: Your Rear Pads in Most cases for that Particular Vehicle Sometime the New Pads come with Rubber Shims,These will go on the Back side of your Inner Pads on Both Sides. Just Reverse the Removal Procedure And Your Good To Go.Don't For get to Check the Fluid Level in Your Master Cylinder.Top it off if Need.

How do I get the rear brake cylinder depress back in when putting on new brakes.


If it does not push back with a c-clamp,then it will turn to go back in,the right side,and the left side will turn either left,or right hand to go back in,depending on witch side you are working on.

How do i change both front and rear brake pads on a 2004 mazda rx8?


CHANGING FRONT BRAKE PADS
Jack up the car. Take off your tire. Find the bolt on the back of the caliper and take it off. This should release the caliper, pull the caliper off the disc. Now you should be able to take the pad out. Replace the pad. You'll need a special tool to reset the caliper. As the brakes wear down, the caliper gets tighter so the brakes still work. I'm not sure exactly what its called, but you can borrow one from auto zone. Follow the instructions that come with it to reset the caliper. Slide the caliper back over the disc. If it doesn't go on, you need to reset the caliper more. Put the relese bolt back in. Put your tire back on.Drive slowly and test the brakes.
CHANGING THE REAR BRAKE PADS
The rear brakes on the rx8 are a bit different than most setups...be careful! The only way to move the piston back into the caliper is by way of a special allen head bolt that is directly behind the piston, on the back side of the caliper, installed under a 14mm bolt.
You have to remove this bolt to gain access to the allen head. As you loosen the allen head bolt(counter-clockwise), the piston will move back into the caliper.
Installation is pretty typical, again, the allen head bolt being the unusual part. The manual says to tighten this bolt until the pads contact the rotor, then loosen the bolt 1/3rd of a turn, then reinstall the 14mm bolt.
