I am trying to use hawk hp plus hb100n pads on my 88. The inboard pad hits the knuckle where the caliper mounting bolts go through. I already drilled the holes for the pins and filed the sides for the outer bracket but they still won't fit. Please help!

I'm not a brake expert but you shouldn't have to modify your pads. The 88's as you probably know have a different caliper and they may have sent you pads for an 84-87? Just my 2 cents.

They are an 88 only upgrade. Looks like I need to grind off about 1/16" from the brake caliper mounting bosses on the knuckle. I wish someone would tell me how they made theirs work because I am afraid grinding on the knuckle will cause it to fail

Based on the first two sentences quoted above I'd say you've got the wrong pads, or pads that are not intended to be used on an 88 Fiero. There are several companies that make brake pads for the 88's, and a few really good ones (EBC green stuff).

He is trying to adapt common off the shelf racing pads with a wide range of available compounds to the 88 caliper. It is quite common as the pad compounds available for the 88's are much less than the 84-87.

You might want to PM Steven Snyder as he has adapted other pads to his 88.
