CPP Disc brake caliper question.. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

IHutch5R · 06-04-2016, 12:25 PM

I've got my disc brake conversion all on the truck but in the box the calipers were in were these washers and I can't figure out where the darn things are supposed to go. There are two for each side and there are two mounting bolts that they fit on, i just cant figure out where they are supposed to sit. If anyone has done this kit before and can tell me or just knows, it would be much appreciated. I want to drive this thing already.

Those are copper crush washers for the brake line, where it attaches to the caliper.

Sorry.. I meant to add that. I have the washers for the brake line though. So I'm not sure what these are for.

Are you sure the ones for the brake line were copper crush ones? If so, then maybe they were extra.

**The Rocknrod** · 06-04-2016, 10:39 PM

Ya if they're copper they don't go on the suspension or chassis.

My CCP kit came with 2 extra crush washers

Same here.

What is your plan for brake lines? I have the rubber hoses about 12" long but not really sure how or where to mount them to the new crossmember ('81).

I put new pre bent lines on it a while back and just used the rubber lines that came with the kit that go from the hard line to the caliper.

dracko · 06-10-2016, 10:42 AM

Oh okay thanks. You still running the original crossmember? I'd buy prebent lines too but I prob won't have the prop valve in the stock location. Did you need to weld mounting tabs on the crossmember where the hardline/rubber line meet?

IHutch5R · 06-10-2016, 10:50 AM

Yes original crossmember.. mine have those little through hole tabs on the A arm that the hard line and the rubber line join in.

dracko · 06-10-2016, 04:31 PM

Ahh gotcha...think I might just cut those off the old one and weld them up on the new arms.

IHutch5R · 06-10-2016, 04:45 PM

What crossmember did you do?

dracko · 06-10-2016, 04:49 PM

It's a 1981 crossmember

IHutch5R · 06-10-2016, 04:54 PM

Oh okay.. do you still have the old crossmember to get the tabs off? They are actually on the side of the coil springs housing.

dracko · 06-10-2016, 05:00 PM

Ya I just went out and cut them off, they'll work perfect once I decide where to tack them on. Thanks!

IHutch5R · 06-10-2016, 06:33 PM

Right on!
