Ford Racing ABS Installation

[GlennCMC70]

Why not behind all the ABS parts? Or is it a dual rear line set-up w/ this ABS?
Is there no F/R bias'ing taking place in the ABS itself? I would assume so since the car reacted the way it did after the install.
Would the better solution be to bias valves behind the ABS and dual pressure guages to keep them equal?

Glenn,
The unit does handle F/R split, but was based around the S197 caliper volumes. Mine are a bit off from the stock system.

It is a 4-channel system, so it's either 1 in-line before the HCU, or dualadjusters like you suggested with guages.

Would the S-197 calipers be a simple bolt-on to your car?

From my discussions with other folks, no... unfortunately.

Guess we are back in business.... Okay, back on topic.The FR ABS was "interesting" this weekend. With StopTech's and GT stock rear calipers using PFC01 and PFC97 front/rear, there is WAY too much rear bias. Under trail braking, the back wanted to rotate VERY badly under release. I had to be very consious of my technique. I'm going to install an in-line bias adjuster BEFORE the HCU on the rear brake supply line. That "should" limit the line pressure and provide less rear "bite".I'll update again around MSR-C time. I plan on testing at least once since the motor is now hurt and need of TLC... (see the "What Happened?" thread).

fwiw the only time I had issue with the car wanting to rotate more than normal was one time I went very late into braking at TWS and came off very abruptly...totally driver error. I found the car very very compliant under breaking....I really felt comfortable ...right up until...btw...the pads have been shipped from the mfr's US QA team to the engineers in Germany for more detailed investigation....I'll keep you posted.

All,
I was also told that the rear left tire was smoking under braking, so the ABS was having some issues getting the bias right. I think the prop valve will help that out, but from the driver's seat with data aq, it will be damn difficult to dial out just the right amount of rear brake (since axle hop is not an issue on FOX's).

...I found the car very very compliant under breaking..

now that's funny right there...I don't care who you are...
