1979 Ford F-350 W/460, C6

Review by Anon from , on 11/25/2023

Reflared fittings for different size as instructed, made changes to 2-wire lead to sensor to make it 1-wire, and the brakes worked afterwards with a 1900lb payload in the bed

Appears to be quality built

Appears to be quality built found that the rear brake line port is a larger size had to go find an adapter to make it bolt up the the lines.

Used this on a 78 Ford E350 motorhome. work great. Had to add fitting to the proportion valve so lines from the M/C would fit

Review by Scott Thomas from , on 4/23/2018

Fits just like factory proportioning valve only thing different was having to use adapters on 2 fittings to change sizes to fit the valve which y'all had already instructed me I would have to do thanks I will definitely buy again this is the second purchase anyway!!

Worked great

Review by Steve Lopez from , on 3/7/2017

The web site indicated that I'd need to swap the front and rear lines and get adapters up at the master cylinder, but on my truck that wasn't quite right. In my case, the front supply line was correct, but the rear needed to be re-flared with a 7/16" flare nut. Other than that, install went fine and the shape fit all the line lengths. That was the only part of the brake system other than the hard lines that I hadn't replaced as new so I was glad to find it. Thanks!

Hard to Find

Review by David from Enid, OKLAHOMA on 10/10/2015

After several weeks battling a brake issue, I diagnosed this valve as being faulty. Trying to find a replacement was almost impossible until I saw this ad. After great communication from their customer service, I ordered the part and it was shipped the same day. Great service, great price, fast shipping and quality parts. What else do you need, I will definitely use these guys in the future.
