    CSRP Disc Brake conversion with MS booster questions

    Hey guys I've finally gotten my floors all welded in and the next project I'm looking to take on is a disc brake conversion for thee front. I've been reading up and I think I'm going to be using the CSRP disc brake conversion so that I can keep my fathers old wheels on it. I've heard some talk of using Mustang Steve's brake booster with this setup and I was curious as to why some people have been doing this and what the benefits are over using the CSRP brake booster. If there are any other disc brake kits that you guys could also recommend to look at before I make any final purchases that would be great!

    Don't know about the CSRP booster but I used the MS booster/pedal mod with stock KH front brakes (same as CSRP, I think) for many miles and it worked just fine.  The MS setup uses a stock Fox 9" four cyl. booster so you will always be able to find one if needed.  It also modifies the pedal to provide the proper ratio for power brakes.

    Re: CSRP Disc Brake conversion with MS booster questions

    Pretty simple answer...
    The csrp booster is a chinese generic that bolts on easily but does not change the pedal ratio.  The mustangsteve setup uses a ford booster and a revised pedal ratio to make the brakes work properly.
    If you tell Dennis at csrp you are using the mustangsteve booster with his brakes, he will supply the correct 1” bore master cylinder.
    While his disc brake kit is an excellent kit, the tube nut fittings he supplies with the tubing are chinese undersized junk. Half the time, they just strip out. Replace all the tube nut parts with good usa parts and it will work fine.
    I have personally installed several of his kelsey hayes type caliper kits and everything works great except the fittings. And I always throw away the flexible and hard line master cylinder tubes and make new ones from scratch.  It just makes for a cleaner assembly.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Re: CSRP Disc Brake conversion with MS booster questions

    The 9" Fox body 4 cyl booster that we use is larger than the standard 7" boosters on the market.  The standard (stock bolt pattern) 7" boosters on the market are really best for six cylinder cars.  So the one benefit of the 7" booster is that it's compatible with the stock bolt pattern of the stock pedal supports.  Disadvantage is that it doesn't provide adequate assist for V8 cars.   Benefit of the 9" Fox body 4 cyl booster (and with the change in pedal ratio at the brake pedal) is that it provides far superior braking assist.  We have kits for automatic cars that are ready to bolt in and doesn't require you to change the stock pedal support or brake pedal.  Hopefully this helps!
