hard to find item, great fit thanks

I have converted my 1968 Cougar from manual drum brakes to power disc brakes, using all 1970 disc brake parts & components. When I got to the distribution block, I at first rebuilt the original core block from the parts car with WCCC's expensive "rebuild kit" with new o-rings. Very soon, the block started leaking from the brake switch, meaning that the brand new o-rings were not doing their job. Fail #1. That's when I decided to try one of these new repro blocks.

First attempt with repro block: as soon as I started to install the new distribution block on the fender apron, one of the mounting studs broke clean off with very minimal tightening. Fail #2. Returned to manufacturer in exchange for another one.

Second attempt with repro block: got the replacement and luckily the studs were sturdy this time and it mounted to the car without incident. Hooked up all the lines, bled the system, and did some braking trial runs in the driveway. Parked the car and... oh look, it's leaking. Fail #3. The problem ended up being simple, but should not happen... the copper washer under the brass nut / fitting on the top of the block had a manufacturing defect, giving it a slight crease in one spot, on both sides. Once I removed it and spent some time sanding down both sides of the washer to make it perfectly flat, and also sanding the slightly rough brass surface of the block where the washer goes (for good measure) and buttoning everything back up, the leak went away. Everything seems to be working properly now.

So, despite the frustrations and multiple fails, I still think this is a decent quality product that just needs a little more attention to detail / quality control. It's made from the proper materials and fits the car / brake lines just as it should. Functionally it seems to do its job fine, but I need to do more trial runs on the road before I can really be sure. As an alternative to a tired original, this'll do... especially when the rebuild kits for the originals aren't made properly. When you're talking about brakes and safety, I didn't really want to rely on 45-year-old o-rings, so it's nice to have something that's all-new.

Short story long... I completely replaced all the brake lines and hoses in my '73 Cougar with stainless. I used a Muscle Car Research rebuild kit on my distribution block since the seals were pushing 40 years old (it was still leak-free though).



After bleeding everything, I found a leak coming right out of the brake warning light switch on the distribution block that I just rebuilt. No fluid should even reach that switch. The new seals I installed were leaking. I am not blaming the kit. The instructions were straight forward and the bore in my block looked flawless. I must have screwed something up.



Not wanting to mess with it further, I bought this block and a tool from Muscle Car Research to keep the brake light switch piston centered while bleeding the brakes. I installed the block and completely rebleed the system. No leaks and after the initial pedal travel slop, the brakes are rock hard. If things change down the road, I will update my review. So far so good.



The lines threaded in easily and it appears to be very accurate in terms of dimensions and appearance to the original part. My only ding on craftsmanship comes from the small amount of brass shavings that were left in a couple of the tapered surfaces onto which the brake line flares seat. Some I could pick out but a couple were still attached to the block. My stainless lines sealed against them nonetheless without having to use excessive torque on the line nuts. Maybe I’m just picky.

The distribution block is the design used in 71-73 cars. I tried to overhaul the OEM one, but it failed. So I bought this one from WCCC. It looks and fits exactly like the original. Works without any problems.

Exact fit work well for a month . Until the plastic brake light warning switch started leaking . Squirts right out center , i guess ill have to call and see if i can get new switch , hopefully under warranty . In meantime Im getting plug lol.
