Brake pad shims project Scrappy.

Postby nlovern » Sat May 16, 2015 1:18 pm

Hope everyone is have a good riding time this spring/summer. Ive been working on Scrappys rear brakes and only part that is rusted beyond reason is the thin brake pad shim. What is it used for/does it do? Where can I get 3 for Scrappy? Or can I make some?
I haven't pumped the caliper up fully but I noticed a lot of space between the piston and pad, about 1/4 inch.I thought new pads with piston seated would be little space at all. I know the shim is very thin.
Im making me a PVC intake and gonna use a VW solex pit3 carb and flexable 1 1/2 exhaust on Scrappy.
May do a Avengers theme on the bike to. My mind dreams a lot.
Take care and watch out for deer and beevcoons in the road :-)

Are the discs the correct width? After so much sitting time, they may shrunk 8-)

But seriously, you should measure the discs to make sure they are still in spec.

The shims are just for anti-noise/squeel. They're not necessary. I've had brakes that were noisy with them and brakes that were quiet without them. CRC makes some anti-squeel stuff you can apply to the back of the pad, too. As far as the space between the piston/pad/rotor, it's normal if you pushed the pistons all the way back into the calipers. Just pump em up.

Those shims should be stainless steel. Are you sure they can't be cleaned up and re-used?
