Default Brake Question

Why are the inside front brake pads worn completely out, and the outsides are really good? They are both worn evenly but the inside ones are toast?????

Sounds like the caliper pins were not lubricated properly and the caliper bound on the pins. The piston forced the inner pads against the rotor when you applied the brake, but because the caliper couldn't move on the pins it could not draw the outer pad against the rotor.

Use a high temperature brake lubricant on the pins, and be sure the caliper can slide on them. Do both the upper and lower pins. Don't over lubricate them, just a thin layer along the length of the pin is all you need.

Something is definately binding ......

Go look at the brake set-up and picture this .....

Remove caliper, then caliper bracket, then rotor. Now picture installing the caliper bracket WITHOUT the rotor. You can now slip the caliper onto and off of (assuming all is properly lubricated) the mounting bracket .... only the rotor actually holds the caliper in place. Withou the rotor the caliper will just fall out of the bracket.

If the pins are properly lubricated the rotor helps "center" the caliper. Something is causing your calipers to not center on the rotor. Maybe material (maybe excess lubricant) has built up inside the caliper bracket where the pins need to slide in.

I'd remove the caliper and the caliper bracket. I'd clean the bracket using a solvent and whatever brushes or other tools allow you to ensure that the cylinders that the pins go into are clear of obstructions, dirt, excess lubricant, etc.

I'd then put the brackets back on the car. Then I'd take the pins, clean them using solvents to get all dirt, grease, etc off them. I'd then put a thin coating of hih temp lubricant on the pins and make sure they can easily slip into and out of the caliper brackets.

If all is fine at this point, I'd go ahead and install the pads and calipers using the clean pins and then bolt the pins to the calipers.

Hope this helps.

Pins should be relubed everytime you replace pads, check pins that appear dry for wear. May the force be with you...
