Title: Front Brake Pad Wear
Post by: beercheck on July 08, 2009, 06:31:55 AM

So, who's got knowledge/theory on what would make my inside brake pads wear twice as fast as the outside pads?  My insides were totally spent, while the outsides had right around 50% left.

The stopping is fine, the rotors are fine, and there never appears to be any dragging, pulling, sticking, or whatnot.  Both the driver and passenger sides are wearing equally.

I have the XL-7 brakes (front, rear, and antilock) directly transplanted onto the Tracker.  In operation, everything works perfectly, regardless of conditions.


Is it simply that I'm applying less brake pedal pressure than would be required on the heavier truck (In fact, I'm generally exceptionally easy on brake pads, so that effect may be even more exaggerated).  Would it really make that much of a difference?

The sliders are probably sticking.

You're using "floating" calipers - where the piston pushes the inside pad against the disk and the caliper pulls the outer pad - problem is the caliper has to ride on the sliders (in this case two pins) for it to work, so if there is any corrosion or binding preventing the caliper from sliding freely, the inner pad wears faster and if one pin is tighter than the other, the outer pad will also wear at an angle.

Remove the calipers, pull the pins out, clean the pin holes with breaker cleaner and a rag, and lube properly - there is a special grease for this
