Brake Rivet Problem

I am trying to replace the brake linings on my Cherokee. I have had new
linings and brass rivets for some time now, along with a rivet tool.
The problem I'm having is that the rivets aren't forming a decent head,
but are simply being "squashed" more or less. They are spreading
slightly, so the result is a tight fit, but I don't think that they're
spreading enough to form an adequate head.

The holes in the backing plates do not look oversized, and I am using a
brake rivet tool, so I'm not sure of the problem.

Any suggestions?


Thanks,
JKG

Put 'em on and use them.

Yes, I'm not sure whether they're supposed to be like that or not. The
ones that came off of there had nice large, rounded lip heads, but who
knows when they were put on or by whom, because it was long before I
ever owned the aircraft.

I just don't want to put them on and have them come flying off.

The heads on the rivets that I installed on my brakes are smashed like
you said yours were. If the brake pads are solid then use them If they
come flying off of there, which is highly unlikely, then put new ones
on. I have had brake lines break on 3 or 4 occasions and shoot all the
fluid out the crack. One operating brake is plenty.

I had a local mechanic finish mine up, and the rivet heads are a little
better but not much--they're pretty much smashed. So that's the way
they're supposed to be, I guess.

The most important things are that the pads are being held tight, and that
you didn't smash the rivets so much that the pads crack.

When you say smash do you mean hammer? Brake rivets should be squeezed not
hammered.

I guess they can be hammered if you're skilled at it, but I think that
he's referring to the head of the rivet, which looks "smashed" by the
brake rivet tool.

In my case, the linings were tight, but the rivets didn't look like the
factory ones, so I wasn't sure whether I was missing something.

The factory puts them on with a roto-pien (sp?) tool. You won't be
able to duplicate that. The rivets are a shear device and carry very
little load under tension. I always put them on with a light hammer
and only tight enough to secure the pad tightly. You don't want to
crack the pad.

Sorry. Probably a poor choice of words.
