The front caliper piston may not be retracting properly due to issues such as air in the brake lines, a damaged caliper seal, or a malfunctioning brake hose. These issues can prevent the piston from retracting fully, leading to brake drag and reduced braking performance.
You can use a large C-Clamp to compress the caliper piston.
Dual piston caliper, 85 ft lbs. Single piston caliper, 37 ft lbs.
Use a screwdriver to lever piston back (between caliper and front of piston). remove caliper, usually two bolts, remove pads from caliper, fit new ones same way. re-fit caliper.
Yes, the caliper should slide with little effort with caliper piston retracted.
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
Use a screwdriver between caliper and front of piston to squeeze piston back, remove caliper via two bolts on rear inside of caliper. Slide caliper away from rotor and support to ensure you don't damage the hyd. hose. Remove pads from caliper, fit new ones same way. re-fit caliper.
You have to have a air compressor to do it. Take an air gun and insert it in the hole on the caliper were the brake line goes to it. Then take the piston in one hand and start it in the caliper while you are blowing air into it and the air will push the rubber boot out around the piston as you push the piston in. It is alittle trickey, But that's how you do it.

If you can't compress the piston with a C clamp back in to position to fit the new brake pads I would suggest replacing the caliper completely.
AnswerRaise and support the vehicle w/ jack stands. Remove the front wheel assemblies. Remove the two bolts holding the brake caliper onto the hub assembly. Slide the caliper off of the rotor. Be sure to compress the caliper piston back down, w/ a c-clamp or caliper piston tool. Install the new pads, reassembly the caliper to the hub assembly, properly tighten all bolts. Reinstall the wheels and lower the vehicle. BE SURE TO PUMP UP THE BRAKE PEDAL BEFORE MOVING THE CAR! I say that from my own personal experience....Good luck!
replace brake hose they colaspe
