There is a special tool you could buy somewhere online or at your local dealer. Basically turn your piston clockwise and you will compress it, but to turn it you need that special tool, or try needle nose pliers and alot of elbow grease
You can use a large C-Clamp to compress the caliper piston.
with a C clam , make sure the you use sameting to protec the piston
some model's that have the parking brake Incorporated into the rear caliper, you must compress and turn the piston until the proper clearance is obtained.
how do you change the brake pads on a 2003 S10 BLAZER To change the front pads you need to jack up blazer and pull off wheel.the brake caliper is held on by two hex head bolts.Remove these and gently pry the caliper up off the rotor.You will need a C- clamp to compress the piston back into the caliper ,so when you install the new pads ,the caliper will fit back over the rotor. put the two hex bolts back in ,and your done.
Using a C-clamp and a piece of plywood to protect the piston. Also, open the bleeder nut when you start clamping down, to let out the pressure. Make sure you have some way to collect the fluid that comes out, it will make an amazingly large mess on the ground and be extremely difficult to clean up.
turn the centre clockwise while applying pressure at the same time, their is a tool for doing this but I just use an old socket which I welded two peices of 6mm bar to the correct width apart so that they locate into the two small recesses in the centre of the caliper, you can then use an extension on your rachet to turn the piston of the calliper while pushing in on it at the same time.
you need a caliper piston tool from autozone..and pads first and then you take caliper off of car and use tool to suppress the caliper piston.by using the old brake pad.the tool cost about.6 or 7$ that should do it for you
That is not a easy job, just because you need to push piston in, and you have to turn it at the same time, but to tak the caliper of and rotor is easy.
I'M NOT exactly sure what you're asking but I think I know. Here goes: I think the problem you're having is that you can't get the caliper assembly (that the new pads sit in) back on, over the rotor. This is because as the old brake pads wore down, the piston inside the caliper moved closer to the rotor. What you need to do is take the new pads out of the caliper assembly. In the center, you will see the round solid end of the piston. What you have to do is get the piston pushed back into the caliper. Try using a LARGE "C" clamp. One side of the clamp on the caliper backside and one side of the clamp on the piston side. Carefully squeeze the clamp together, and the piston will very slowly go back into the caliper. Keep squeezing it until the piston goes all the way back in. Now when you put the new pads back on the caliper, there should be enough room between the pads to slide it over the rotor. Hope this answered your question! Good Luck!! <<ADR>>
you take out the 2 bolts that mount the caliper to the caliper mount. Then you take a small pry bar and push the brake pad closest to the caliper piston so you can get the caliper off, if it doesn't just slide off. then you take one of the old brake pad and a vice grip clamp, you put the brake pad in front of the piston and put the clamp on the brake pad and the back of the caliper and clamp it down until it will fit over the rotor with the new pads on.
I believe on this model you need a special tool to push the piston back. You can go to the website I have below click the link below!
Jack up car and remove wheels, using14mm wrench remove both caliper bolts, remove caliper and pads, using special brake tool from autozone which twistes the piston back in so the new pads will fit, use wire brush to to smooth rust from sliders on caliper then hit them with brake lube , after pushin piston all the way in with tool install new pads ad replace caliper and bolts
