clutch master cylinder failed?

[rdorman]

You say you adjusted the bias until the rear stopped locking up. Am I to assume that the fronts now lock first? If so, where is the balance bar set in relationship to the master cylinders and brake pedal? Is it roughly centered or....... measurements will be handy. Make sure that the bar is perpendicular to the pushrods when the pedal is fully depressed, that the master cylinders can fully return and that there is no binding throughout the travel.

No, the front end does not lock up, it just nosedives!
I threaded the rod in the bias bar towards the front MC, I would say there is about twice as much threads showing on that side. I presently have no fluid in the rear MC so I can't do as you requested

I got tired of crawling into the foot box to adjust the brake bias, so I installed one of these - http://www.wilwood.com/Products/005-...RBBA/index.asp A Remote Brake Bias Adjuster. Kind of like a quick change rear-end - works like a charm

Phil,

I am going to order one for my FIA Roadster as I too am tired of trying to fit my "large body" into that tiny foot well to make adjustments! I've always had a brake bias adjustment in the cockpit on my other Cobras and race cars over the years but they were the "in line" variety with a tandem master cylinder rather than a dual cylinder balance bar set up.

Regards,

Yeah, that is pretty neat...what was the cost?

[pgermond]

$60, although it's been 4-years so the price has probably changed. What ever increase has occurred - it is worth it.

[davids2toys]

Thanks a lot

my car came with an "in line" type adjuster. I plan to use it again, any Pros or Cons out there?

I think all you can do with that type adjuster is change the fluid pressure to either the front or rear brakes, which ever line you install it on, it is not a bias adjuster.

Wouldn't the end result be the same?

Wouldn't the end result be the same?

Yes - result is the same. Lower pressure on the caliper pistons generates less force on the pads. Adjustable proportioning valves (like this) are used a lot on cars with "regular" tandem master cylinders - i.e. where you don't have a balance bar.

Geez - this doesn't translate into print very well.

I disagree... great job!
