what is the best way to bleed brakes when installing new caliper on front left wheel
You need a 3/8 Allen key to release the caliper.
The caliper is one part of the brake system.
It is normal for caliper brakes to maintain very slight contact between the pads and the rotor. If that isn't what you're referring to, about the only things that would prevent the caliper from releasing the rotor would be either a seized caliper piston or possibly a bad proportioning valve.
Disc brakes at the top of the caliper Drum brakes at the top of the wheel cylinder
Should be disc brakes and not adjustable caliper slides to compensate for lining wear unless caliper slides are frozen
THERE ARE TWO BOLTS ON EACH SIDE OF THE CALIPER REMOVE THOSE AND PULL THE CALIPER OFF
Frozen brake caliper
be sure to purcahse the tool to "screw" the caliper piston in. If you try to push the piston in on rear disc brakes you will damange the caliper.
It is a special bolt/pin that allows the disc brake caliper to float. There is usually two per caliper.
Jack up the car. Take off your tire. Find the bolt on the back of the caliper and take it off. This should release the caliper, pull the caliper off the disc. Now you should be able to take the pad out. Replace the pad. You'll need a special tool to reset the caliper. As the brakes wear down, the caliper gets tighter so the brakes still work. I'm not sure exactly what its called, but you can borrow one from auto zone. Follow the instructions that come with it to reset the caliper. Slide the caliper back over the disc. If it doesn't go on, you need to reset the caliper more. Put the relese bolt back in. Put your tire back on. Drive slowly and test the brakes. Hope that helps at least a little bit.
