Go to your local auto parts, they have a non expensive tool for this. Use the old pads to when compressing.
To compress the rear brake caliper piston on a 1995 Buick Riviera, you'll need a brake caliper tool or a C-clamp. First, remove the caliper from its mounting bracket and support it without stressing the brake line. Then, place the tool or C-clamp over the caliper piston and gently compress the piston back into the caliper housing. Ensure you also open the brake fluid reservoir to prevent pressure buildup, and check brake fluid levels afterwards.
Shade tree mechanics use a C-clamp and a flat steel bar to compress the piston. I have also used a large adjustable Channel-Lok-type pliers to compress.
If they are the same as a 97 Maxima then you twist them, don't compress them. To compress the piston you do it with a 'Disk Brake Piston Tool'. You can get this at Pep Boys for $12. To compress the piston on the passenger side you turn the piston clockwise. To compress the piston on the driver side you turn the piston counter-clockwise. Be careful trying to turn the piston using pliers or some other tool as you may tear the rubber seal around the piston.
Clockwise to retract piston into caliper body
You can use a C-clamp to compress the caliper on just about any vehicle. You might want to place some rags near the Brake Master cylinder because brake fluid will travel back into it from what is left over in the brake lines. If you don't, you will spill brake fluid onto the floor.
To push the piston back in the caliper of a 1995 Mercury Tracer for new brake pads, you can use a C-clamp or a brake caliper tool. First, remove the wheel and then the caliper. Place the C-clamp over the caliper and position the clamp's screw against the piston; as you tighten the clamp, it will push the piston back into the caliper housing, making space for the new pads. Ensure the brake fluid reservoir is checked to prevent overflow during this process.
Use a large C- clamp to depress the piston enough to remove the caliper.
there are 2 ways on is with the C- Clamp. when tightening the clamp loosen the bleeder valve. the second is have to use the caliper tool to screw in the piston steve@spider-technologies.com
To rotate the piston back into the caliper of a 1995 Lincoln Mark VIII, you should turn it clockwise. This model typically has a threaded piston that requires clockwise rotation to retract. Make sure to use the appropriate tool designed for this purpose to avoid damaging the piston or caliper.
Typically, you take one of the pads that you removed, place it on the piston and use a large clamp to compress it back it. Some vehicle have pistons that screw in. Most autoparts stores have a free loan a tool program, where you can get a tool specifically designed to push the piston back in. If the piston is ceased and won't move, then you'll likely have to replace the whole caliper. After market parts are cheap and a rebuilt caliper is about $125. The 1995 has pistons that screw in I rented a tool from Auto Zone that made it a snap.
the piston on the rear calipers will turn in a clockwise motion and that is how they retract.
The rear brakes you need a 3/8 standard wrench to open two bolts retaining the caliper. The piston caliper requires a special tool to "wind " it or screw it back in order to install the new brake pads. DO NOT PRESS THE CALIPER PISTON BACK. You have to "screw" or rotate it.
