No, to be honest I lost my patience with the overall CPP experience. I hit a wall with the response I received over the phone. It probably would have been wiser to check with you first, instead of wasting some much time on hold and trying to get someone live over the phone.

OK I know this is a very old thread. I was researching CPP brakes and came across this. Looking at the top left picture, it looks like MAYBE the backing plates were not installed correctly, and cdowns also noticed the one in the picture appears to be crooked.

It appears the backing plate bolts are in backwards, with nuts against the axle flange, then the backing plate installed atop those nuts. This would pull the outboard pad towards the backing plate too far and drag against the rotor (pad cracked from over-heating), and also this would pull the pad toward the top of the rotor (off the edge, note the lip on the top of the pad). This would also cause the inner pad to dig in at the inner radii of the rotor, and possibly leave a lip at the top as well.

I would suggest that the backing plates may need to be installed with the bolts going in through the backing plates first, then flush against the axle flange, then with nuts on the other side without excessive bolt protrusion pointing towards the wheel.

I could be wrong, but I'm wondering if Jeff at CPP could confirm if that is indeed the right way to install the backing plates. It only took me a minute to find this, not sure if it was available in 2010.

I'd be shocked if the kit didn't come with instructions. Even if it didn't, don't those bolts usually go in inboard towards outboard? Just a thought, seems CPP got skewered and I'm not sure that was necessary.

Actually, I think 68 c10 ls2 has the Backing Plates on backwards, (side for side).

Yeah they pave the roads here before they need it. Cross over into Phoenix and it can get bumpy in a hurry.

Yes, they are smooth when they aren't barricaded. They dig up the pipes every couple of years as well need it or not. Somebody is getting their pockets lined, for sure.

City sales tax is 2.9%, total sales tax 9.2%. Less where you live?

Andy4639 · 10-31-2014, 09:47 PM

Well I will be calling Jeff Monday. I just spent 10 solid hrs on them and I don't have brakes yet. I finally got the passenger side done but had to take it off 2 times before I got it right. I completely left the spacer bar off and it seems to fit good. The directions should state this!!!!

The drivers side is another story. I took it back off and removed the spacer bar and it didn't have enough clearance so after reinstalling it I figure it needs to be shaved in half and it should work. I HOPE ANYWAY!

The hard lines don't fit the stock truck Tee connection. I had to go buy adapters from O Reillys for that.

Andy4639 · 11-01-2014, 09:03 PM

20 hrs total spent on this install. The kit sucks! I do have them installed but I wasn't happy at all with it. I had to buy parts from my local parts store and I was told this kit was for a Chevy truck 12 bolt. The instructions all state Chevelle and Camaro nothing about trucks. The hard lines didn't fit the Tee connection to small and the bracket they have didn't fit the S/S braided hose fitting to hold to the axle.

The spacers are not used on either side. I had to use 3 washers on the drivers side and nothing on the passenger side. I will get the spacer machined down to reinstall on the drivers side. The t-bolts are not grade 8 so I will swap them also. The calipers are a ***** to adjust. I followed their instructions to the tee and I have pretty good brakes but I don't think the kit is very well thought out are user friendly!
I sent CPP a e mail telling them how much I disliked the kit and what all the problems where.

ksbrktracer · 11-03-2014, 11:33 AM

Im wondering if you got the wrong kit ... If the instructions say chevelle and camaro ....which would be same , but different than a truck. If you have a part # I can look it up to make sure you got the right kit.

Rochlow · 03-22-2015, 10:21 PM

I have 6366FRBK6-BB 1963-66, 6x5.5 kit, plain calipers and I spent the whole day trying to get fluid threw the master cylinder and the lines.. Once, I finally got that done,I couldn't get the pedal to firm up..

blackbart63mule · 03-22-2015, 11:12 PM

U may have to "bench" bleed your master cylinder, or try drawing fluid thru wheel cylinders with a mity-vac, or vacuum pump.

Rochlow · 03-23-2015, 09:29 AM

I did bench bleed the M/C and I have 4 wheel disc brakes.

blackbart63mule · 03-24-2015, 09:18 AM

Some proportioning (stock) valves had a pin you had to pull out to bleed front or back brakes.

Rochlow · 03-25-2015, 04:34 PM

It's a CPP portioning valve, there is no pin to pull out

blackbart63mule · 03-26-2015, 12:07 AM

Maybe you got a bad master cylinder if it was that hard to bleed the system the first time, I've seen brand new ones that were pitted in the bore. Had one that after I bench bled still had 'microscopic' bubbles in fluid, I let it sit overnight and bled it again.

Possmguts · 03-26-2015, 09:04 AM

Im doing the Wilwood thing. Ordered the rear kit last night. I think im gonna use the entire Wilwood setup. MS and all

Im wondering if your pedal shaft to MS needs adjusted is all... If its too short your pedal is not going to push far enough to do anything. Just a thought

Rochlow · 03-26-2015, 04:40 PM

I have been adjusting that also. its adjustable from the pedal to the booster and from the booster to the M/C..

Skeetman · 12-02-2015, 05:13 PM

CPP REALY SUCKS and I'm being kind should say something worse.
Bought a Pro-Touring Kit for my '67 Cutlass and their customer service is poor no mater how much money you send with them. One rear caliper leaked as I bleed the brakes for the first time they replaced it after numerous phone calls claiming it was my fault. The front caliper brackets are crap and so badly warped they could not be mounted square they sent me three sets that did not fit. CPP requested I send back the complete front brakes spindles, calipers and rotors and they assembled them which CPP machined the brackets to fit and cost me $210 shipping both ways. CPP's master cylinder is also crap with the built-in portioning valve does work and CPP would not replace it. I would not buy anything from them. They have too many products and crap off shore suppliers. The brake system I bought is for an "A" Body GM car there are thousands of those cars out there and CPP can not can not get it correct. When I decide to upgrade my '85 GMC brakes I would not buy from CPP for sure.
