Front Brakes pads tight fit

Front Brakes pads tight fit

Postby Maxximum_44 [OP] » April 10th 2012, 7:05pm

Hey guys, I changed the front pads on the 03' and had to knock out the old pads(pass. and driver) with a mallet to get them out. I used two C clamps on the dual piston calipers per FSM.
After greasing and lubing everything as recommended, I put everything back together. My concern is the pads I installed didn't exactly "slide" back and forth on the new guides smoothly. they're a bit tight.
Should I have grinded some material off the tabs or whatever so that they move freely? or do I want them to have a little resistance?

They should be able to slide a little, did you clean the caliper bracket?

If you can't fix it with a hammer you've got an electrical problem!

make sure you clean the caliper bracket really good before you put hardware back on. that should solve your problem.

As the others said, they should move freely, but I wouldn't go as far as a grinder. Propbably just need a good cleaning,scraping, scotch-brite padding.

I wire brushed them pretty good spayed brake cleaner and repeated. Didn't have this problem for the rear brakes when I did them last year.

I'm not familiar with those newer disc brakes. What is the component labeled #4 in the diagram above?

After looking at those old pics from last years job, I noticed why they fit easier. The mounting tabs on the rear brakes are different than the front brakes. Those rears just fell out. I had to pound the fronts out :think:

That #4 piece looks interesting. In my 89 discs, I have the equivalent of #1 (the caliper) plus the piston, plus the two pads (and the long bolts. The pads just sit there. Some of them have a little simple clip thing but essentially they just fall out, as you describe for your rear brakes, when you pull the long bolts.

Disc brakes are cool. One of the easiest jobs I've ever learned how to do. Drums are a PITA. But discs are cool.

haha, never done drums. Hell, this is only my 3rd brake job. Disk swap was pretty straight forward (besides the snug fit up front).
