One side of the vehicle(rear only) will screw in right hand clockwise,the other side left hand.While doing this push in a little bit as you turn the piston.Make sure they go all the way in,and align the notches for the brake pads to set in them.You can purchase the tool cheap at the auto parts store to do this with.It is square with different notches all around it,and it fits on a 3/8 ratchet.I hope this was helpful.if so.let me know,thanks.

When replacing rear disc brakes on a 2004 Cadillac SRX V6 SUV, do I need a C clamp to compress the caliper piston?


Yes, you have to compress the shims on any car with disc brakes to release the pads, I recommend using an actual disc pad compressor tool, C-clamps can cause damage if not used the correct way. Pad depressors are typically $10 bucks at a local auto parts store. Good Luck!

New brake rear discs and pads on a ford mondeo 03 but can not get the caliper pisten to go back enough to fit pads


Loosen the brake fluid reservoir cap to allow pressure to escape. Use a large C clamp connecting it to the front of the piston and back of the housing. Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads.

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.

1996 olds aurora back brake pad replacement, how to compress the pads to get the caliper back over the pads?


Special tool is a 1" cube with tabs on each side that fits into indentations on the brake piston and can be purchased for $10-12 @ most discount parts stores. Use 3/8" ratchet with short extension and 'special tool to carefully turn piston onto internal hand brake screw. Take care to not tear dust boot. When piston is fully collapsed, make sure to align piston indentations perpendicular to brake pad as there are bumps on pad that fit into them. Also while screwing in piston either remove about 2/3 of brake fluid in master cylinder and refil afterwords or open the bleeder valve on brake piston assembly. Bleed if necessary.

How do you compress rear brake caliper?


Dear Sir/madam,

The pistons on the rear brake calipers SCREW in to the caliper. There are notches on the inner edge of the piston face. engage the notches with a large needle nose plier or a large flat washer and turn clockwise (as you face the piston) to turn the piston in.
There is a special tool that is available at your local autoparts store that is absolutely necessary and will save you a ton of time and aggravation. Using a needle nose plier or washer does not allow you to apply enough pressure unless your are the incredible hulk.

thanks
Good luck
