'94 Nissan Maxima SE, Rear Brake Wear Problems
Q:
I have a ‘94 Nissan Maxima SE with rear disc brakes. I changed my
brakes last year and now they are metal on metal. When I changed them
I checked to make sure they were turning freely, so I don't understand
why they’re wearing so fast.........Ed
A:
If the rear brakes wore out that quickly on your Maxima something has
to be going on. The on part has to be the brake pads rubbing too much
on the rotors or you bought low dollar brake pads. Let’s hope that
you didn’t install "pray they stop" brand brakes. The only
reason a quality set of brake pads wear out prematurely is because they
are working too much. Also, just because a brake doesn’t seem to
be dragging doesn’t always mean the brakes are working right. A brake
pad binding in its holder due to rust, corrosion or poor fit will cause
rapid brake pad wear. The brake caliper has to move freely on the slides
and guide pins. Any rust, corrosion or just lack of lubrication will accelerate
brake pad wear. If a quality product was installed then I would suggest
a closer inspection. A little binding in the wrong place can really wear
the brakes.
