On the back side of the bearing, near the break line is a little fitting. i think it is 5/16 in socket. loosen it, so the air comes. then try to hand spin the tire. if this doesnt work then you have to go into the hole located on the same side, about hte size of a peanut, with a screwdriver, and if you can see in there, there is a littel gear that has to be spun. it will loosen the back brakes.

    ok you will have to do what i said about the gear, or, if your willing too, then you can pry the drum off with screwdrivers, working each side left and right. the shoes will eventually work themselves out. you may chip the drum a little but its not that big of a deal

    Ok then bleed out the rear brakes,Do you know how to do this?You dont have to crack the brake line to replace pads,but any way it sounds like you have air in your brake lines,there's an small nipple behind the brake caliper,if you loosing it brake fluid will bleed out,you will need an helper,to add fluid into the brake res,you have to pump your brakes untill all the air out,do one side at a time.

My left rear tire locked up and it feels like the people who did them forgot the other brake pad is that why its locking up"


if they are disk you could tell real easy just by looking. but if its drum you need to remove the wheel and brake drum. check for fluid loss first because if the pad is missing, there isn't anything to hold back the piston inside the wheel cylinders and fluid would run down the inside of the wheel. hope it helps

Front wheel bearings


first check the pads have not worn down to metal if they have the disc will have to be replaced , if the disc is in good condition and the pistons are free press them back into the cylinders and then the pads can removed .check the master cylinder does not over flow as the pistons are pushed back. Brake fluid is a paint remover. the wheel bearings don't have to be touched to replace pads. After new pads are fitted the brakes will have pumped to bring the pads out to the disc.

I changed my front pads and rooters on my 2002 suburban and now the power steering is out?


Phil: you probably got air into the power steering fluid assist piston. Try driving your car. The air should bubble up, keep adding the correct power steering fluid.

Leaking brake fluid from right front wheel 1995 honda passport


Sounds like from what you describe it's a leaking break caliper. The best thing to do is get a rebuilt one. It's best to replace them in pairs. Also replace or clean the brake pads thoroughly!

Had new front brakes done and rotors discs brake pads and it smells like its burning rubber after driving 5 miles back brakes lock up and need to repair as to brake lights are on is this normal or wher the...


the work should be rechecked to make sure nothing is siezed and check the rear brakes to see what is causing them to lock up.if the smell is coming from the front then you could have a caliper that has siezed after the brakes were replaced.this does happen from time to time and there is not a usual way to know before they sieze until its driven unless when pushing the pistons back you notice they are hard to push back.

Want to replace my own front brakes on 2003 outlander. cannot find detailed repair instructions anywhere. any ideas? thanks!


Hello, to replace the front pads first open the hood and remove the brake fluid cover (will make retracting the piston easier). Next losen the lug nuts till you can turn them by hand than jack up the vehicle and use a jack support stand. Once the vehicle is supported remove the lug nuts and wheel, remove the lower caliper screw and rotate the caliper upward. Remove the old pads, use one of the old pads and place it so it centers the caliper, using a large C-clamp position it with the solid end on the back side of the caliper and rotating handle contact the pad in the center or close as possible. Slowly rotate until the piston is fully retracted into the caliper, your brake fluid may run over but its ok. Install the new pads return the caliper to the normal position over the pads reinstall the lower caliper screw. Put the wheel back on tighten the lug nuts till the wheel is evely and firmly in its normal position. Remove the jack stand lower the vehicle, put the brake fluid cover back on and pump the brakes until they are firm and check the fluid, add some if needed. Tighten the lug nuts, check for leakes. After starting the vehicle pump the brakes a few times, now the fun part the test drive :) allow you self more than normal distance to stop. Tips, I always set the parking brake when working on the front brakes, some people use a 2x4 instead of a brake pad to retract the piston into the caliper, double check your work, i always do and take your time.

Since you are taking it back, have them check all the brake lines in front, and the wheel cylinder (if the back has drum breaks). Although you had only the front done, it's a good ideas to have them check the back brakes, and the master cylinder. Check your brake fluid before taking it back and make sure it's full, if so, you may just have air in the brake lines. If this is the case, either they forgot to bleed the brakes, or didn't bleed them enough.
