They can be pried back by force and leverage, but the best and safest way is with a C-clamp

How to replace front discs and pads


Front brakes are very simple to do:
  • Pull off the front tires.
  • Remove the brake pads by removing the slide pin bolts where the piston assembly attaches to the caliper mounting bracket. The slide pin bolts are usually a 12 or 14mm bolt. Once the piston assembly is free slide the old brake pads out.
  • Compress the piston back into the caliper by using a large pair of channel lock pliers or a c-clamp. If you don't do this, you won't be able to get the new pads on.
  • Before you put the new pads on, replace the rotor.
  • Remove the two bolts for the caliper mounting bracket. They are in the back and are bigger than the slide pin bolts. Usually a 17 or 19mm bolt.
  • Pull off the caliper mounting bracket.
  • At this point the old rotor should slide right off. If it doesn't slide right off, look for a screw in the center of the rotor, some cars will have a screw there to hold the rotor on. If there's no screw and it still won't come off, try tapping it with a hammer. If you're replacing the rotor, don't be shy.
  • Put the new rotor on. Make sure to clean off any grease with brake cleaner that may be on the braking surface from packaging.
  • Put the caliper mounting bracket back on.
  • Put the new brake pads on. Make sure to use some anti-squeal grease on the back of the pads.
  • Put the caliper assembly back on with the slide pins. Grease up the slide pins as well.
  • Put the wheels back on.
  • Make sure to pump your brakes 10 - 15 times before you drive off. Because you compressed the piston back into the caliper, the piston will not be contacting the brake pads unless you pump the brakes.

Good Luck!

How do I replace brake pads on 2007 tucson. I


use a 14mm wrench or socket to remove the caliper bolts/slides. remove caliper. note how old pads came off, match the new pads with same location of old pads ( check for hardware or indicator location). press the caliper piston in . the correct way is to use a caliper press, apply a little pressure to piston, open bleeder screw, press piston all the way in, tighten bleeder. (or grab a 'c' clamp and slowly push the piston in. i would recommend having the rotors machined to for proper wear and to eliminate vibration. for this remove 2 17mm bolts holding caliper bracket on and rotor will slide off.

Use a C clamp and squeeze the caliper piston back in. Put the pads in place and try it. That should do it. Remember to push on the pedal a few times before you drive it. Check the fluid before you drive it.

How do you put on drum disk and colaps the shoe pads


If they are drum brakes, make sure you turn the self adjustment screw all the way closed. If they are disc brakes you need to use a brake tool to screw the calliper piston in. Just loosen the bleeder valve and screw the piston in counter clockwise.

Need help changing the front rotors on my chevy 3500 4x4 dually


Have to pull the front wheels, next back out the two caliper bolts (Allen head), next slide the caliper out of it's seat and set up on the spindle, careful not to damage the flex brake line. This will now free the rotor to come off the spindle. This is also a good time to check/replace brake pads. Chances are if your changing rotors, due to brake damage, warped or other, the pads need changed. This is simply done by sliding the old pads out and placing a C clamp over the piston to back it into the caliper housing to allow room to install new pads. Apply a little antisieze lub behind the pad between the piston and also anywhere the new pad bears. Install the caliper in reverse order and put the wheels back on. Remember to test the brakes before hitting the road, The new pads will have to be pushed out by applying brakes a few times. Then you should be good to go.
Hope this helps.
