There's a special tool required to compress the rear caliper pistons. You may want to rent the tool. If you look at the piston you'll see one or two notches. The special tool has nipples to fit these notches. The caliper piston will have to be compressed with the tool and the notches will have to be placed in the o'clock and 6 o'clock for the brake pads to slide over the rotor. If you rent the special tool have the renter show you how to use it.

How to compress back brake calipers when installing new ones


You open the rear caliper bleeder valve as it is
near impossible to push fluid to the front of car

Then you turn the caliper piston clockwise-to turn
in the parking brake adjuster- as you push the piston
into the caliper bore

Two functions-piston turned in & pushed in

You line up the piston notch to the top-so the
round bump on the inner pad goes down in place

After the caliper & pads are on & before you start the
car & bleed the 4 corners & then push brake for a firm
pedal-----You ratchet up the lever on park brake at back of caliper

They don't make a tool for an LS

I took the cube avail at any parts store & filed the outsides
of two pins to fit the piston notches

Need help in replacing front and rear brakes on a 2003 mitsubishi montero full size


Hi there,

The pads are easy to change. You do not need any special tools. If there are no grooves in the rotors I would just put on new pads. Don't get cheap pads or they will squeek. I would strongly suggest that you flush out the old brake fluid. You will be amazed at how brown and gunky the old fluid is. Flushing the fluid regularly will help make your calipers and master cylinder last a long time. I like to use Valvoline Synpower brake fluid, it is a couple bucks more but it is DOT 4.

One last tip. When compressing the brake caliper piston you do not want to push the fluid back up to the system, because you might get some crud into the ABS module. Therefore, when compressing the piston, loosen the bleed screw to let the fluid flow out of the bleed screw.

This is how to get it done:
  • Remove the old fluid from the master cylinder resevior with a turkey baster. Top up master cylinder with fluid.
  • Remove the right rear wheel and bleed/flush the brakes with the old pads on. Top up master cylinder with fluid(important). Remove the caliper, open the bleed screw and compress the piston, close the bleed screw.
  • Install new pad and caliper
  • Bleed again. Top up master cylinder with fluid.
  • Repeat on remaining 4 wheels RR, LR, RF, LF.
Glad to be of help!!!

Brake pad change? On my 2002 Suburban 4WD with ABS do I need to open the bleed screws on the caliper when compressing the piston? Or is keeping the lid loose on the master cylinder and removing some...


If you open that bleed screw to compress the piston you'll have to bleed tha air out of the system, so don't open the screw. Use a 5" or 6" C clamp to compress you pistons IF they are not the screw in type - you can call your local auto parts store to determine that. If they are the screw ins, the parts store may have a piston compression kit to rent you for the job, as the piston would need to be rotated slightly as it is compressed. Do not try to just compress the screw ins - you'll break the caliper and have to buy a new one.
Good luck!!

Can i change breake pads without bleeding brakes as i have read on net that I can compress caliper pistons without opening resevoir and or bleeding lines


Brake pad replacement does not involve brake fluid loss or air entrainment in the brake lines. It is a good idea to loosen the lid on the master cylinder reservoir while you compress each piston. It may make it a bit easier to do. If you do put a rag around the reservoir in the rare event there is slight spillage. Use a small block of wood or an old brake pad as a protective caul to cover the piston end in the caliper, Use a C-clamp or similar tool to gently compress the piston back into the caliper head. When initially positioning the C-clamp, pay close attention to where it will grip on the back of the caliper so you do not inadvertently damage other parts. Once you are all done with the pads check the reservoir and top off with a little fresh brake fluid if necessary. Be sure to securely fasten the lid to the brake fluid reservoir.

Open the bleed nipple while the caliper is tight in the clamp - open it till it weeps and tighten the clamp till the pistons are flat with the caliper then tighten the bleed nipple. you should be able to fit the brakes now easily. Remember to check and if necessary replenish the brake fluid reservoir.

What tool do I use to change brake pads


Use proper sized socket to take out 2 bolts holding caliper on. Lift caliper up to remove. Open brake reservoir top and use old pad and large c-clamp to compress cylinder back in fully. Put squeek-stop on back of new pads and install the way you took them off. Remember where the wear bar on the pad was.Little metal tab on pad. Bolt it back on and you should be good to go. Shouldn't have to bleed system.

2002 tahoe breaks lock up during driving


It sounds like the rear calipers are bad. Raise the rear wheels and see if you can turn the tires. If you can't, open the bleeder. If you still can't replace the caliper. If you can turn the wheel after you open the bleeder, replace the brake hose to that wheel.
