    631014 is rated 4.2 out of 5 by 6.
    Rated 5 out of 5 by from Neat features When I purchased this a month ago, my delivery was canceled because it was damaged during transport. I informed Jegs immediately and a replacement was shipped right away without question. Installation was not as easy as expected. I had to order new brake lines to replace the originals, to have proper connection to the master cylinder, in my 69 resto-mod Chevelle, and made modifications to have the correct line placement for the 4 disc brake conversion. I also had to install an electric vacuum pump to have the right amount of pressure to the brakes, from 10# to maximum 20#s because the original booster was 11” and this is an 8”. I love the clean chrome appearance and it’s working as it should. So far, no leaks...keeping my fingers crossed.

    Rated 4 out of 5 by from nice chrome I have not finished the installation, I did however purchase a flat mounting bracket rather than use the angle bracket that is supplied. Wish you had this choice when placing order

    Rated 1 out of 5 by from Pain in the Works ok, the inputs for the master and the proportioning valve are 9/16” which are hard to find. Does not include the needed plugs for the other side of the master, good luck finding them.

    I'd Like to install this on a 64 Chevy pickup with disc brakes up front and drums in the rear, should I expect issues with the divided application? What amount of reduction in foot to pedal pressure/effort can I expect?
