I have had all kinds of problems with my 4 wheel SSBC brakes over the years and have switched out masters, brake lines, and distribution blocks all with just mild success. They did call for like 500 miles of break in and that did help some. I have pretty much just written them off as an average setup just slightly better than well set up drums. I even have their slotted rotor force 10 aluminum caliper setup that was advertsised as being so great. I do get better repeatablitiy out of them but once again not nearly as good as I thought. Will be going to some type of 13" disk set up like from a Viper before too long. Good luck with yours and hopefully the switch to a 15/16" master will be you answer. Todd

Those calipers have very small pistons. You need to run a 15/16" bore master cylinder.
Also, they will improve once the pads are bedded. For some reason SSBC provides the wrong master cylinder with the kit. the 1 inch boar on the supplied master does not help the situation. Just press harder

Yeah, there tech line was awesome when I was first having my problems!!! Guy told me well that car is heavy, if it is stopping from 60mph in anything short of 200' then that should be considered good. My drum brakes were stopping from 60 at around 150'. Boy good thing I spent nearly $2K on their awesome brakes so that my way heavier Explorer and my wife's fat minivan could stop better than my way lighter(3650 lb) roadrunner. Todd

Sure sounds like Pedal ratio. I just went thru this too. Hard pedal & no way I could lock up anything. Read through this.... http://www.hotrodheaven.com/tech/brakes/brakes6.htmMine is a c-body & there's 2 different pedals for the Power & manual setups. Also 2 different hinge points for each Pedal. Doc diff sent me that link & sure enough my Pedal ratio was 3:1 & I needed 6:1. Modified the pedal & it's much better now. Working on other issues with the Brakes right now. Butch
