I'm trying to install secondary calipers for my ASD hydraulic brake on my FD. I bought this kit from RaceFAB, who told me to use Turbo FC calpers. The brackets and calipers fit perfect with the kit. ASD said to use a 5/8th master, but I'm having some trouble bleeding the system.

We bled it for a few hours today, even took the calipers off and bled them upside down, since the bleeder faces downward. We bled for 3 hours. There are zero leaks, the handle pulls back halfway and feels very mushy, it improved a lot once we started bleeding the calipers upside down but it's still very mushy feeling. On a test drive, the only way to lock the rears was to feint the car and really pull the S out of the handle, not really what I was expecting.

I've been talking to some people some say keep bleeding, some say try ASD's 3/4th master and more than one have told me the FC calipers are crap, unreliable, etc. I guess I could search for a similar size caliper or modify RaceFABS brackets to fit a Wilwood caliper but I wanted to check here for any suggestions first.

Thanks.

bench bleed the master. then turn the calipers upsidedown and bleed the **** out of it. be sure your master doesnt get air in it. make sure the reservior stays full the whole time. (constantly filling it.) you will never get them bled if the air nipple is on the bottom of the caliper. you probably have a ton of air in there that wouldnt come out because of that, and your master probably has air in it too. sometimes its a bitch to bleed. but Ive never heard of anyone having unreliable calipers.

also you can buy some of those quick bleeder nipples from summit that allow air to go out but not come in. they arent much and probably worthwhile.

Thanks for the reply. We bled them upside down for a long time, it was an improvement over bleeding them mounted but still coming up with a very soft handle. Multiple people at my drifting spot, Clubloose in NJ, have said the calipers have problems. I found a local guy that can fab up some brackets for a Wilwood caliper.

Bench bleed the master, buy a mitivac and put a vacuum on the calipers. You will get the air out that way.

Rich - I saw your post on facebook but never got back to respond. I run the racefab brackets and dual calipers on my FC. I use a CNC staging brake with remote reservoir for my hydro (3/4" master cylinder) and the stock FC calipers. I had tons of trouble bleeding my setup but eventually got it to where it works reliably. I used a combination of the mitivac on the caliper end, alternating with standard bleeding with speed bleeders on the calipers. I also swapped the pads from a set of hawk pads to a set of cheap parts store organic pads (Beck Arnley 082-1283) and that seemed to make the biggest difference.

Now the brakes work reliably, but the feel isn't there. I still have to pull the handle a mile and I usually run from the pits to grid and from grid to the first corner on the first run or 2 with the hydro dragging to get some heat into the pads. I really wish that I had stayed with my inline setup since it had great feel and I never really experienced the feed back/ control issues that everyone "warns" you about.

maybe get a 1 1/8th master. I have one I use for my clutch. its super stiff for my leg. I kinda hate it. but the stiff feel is totally there. would probably make your ebrake super stiff. or i would probably start with a 1" master. also use cheap pads like smitty said. they tend to heat up and actually lock rather than slow the rotor down like nice pads do. or throw on some fancy brakes. Ive never actually had a hydro ebrake so I dont know what Im talking about. stock cable works fine on fcs.

Scmitty no worries man, I think my bro and I are going to mod the brackets of have a guy at Raceweld East fab up something for a Wilwood.


uh....thanks. yeah.

^This is how I got mine to work. I bled mine dozens of times over a coupler weeks and I think there's still some air left in it. I also bought new calipers so I knew that wasn't the issue.

Ive never had a hydraulic ebrake on my car. doesnt mean I havent helped many others with theirs.

hah, then don't write this:

just because Ive helped others doesnt mean I know what Im talking about. lol
