Glen,
The suspension checked out fine, nothing out of the ordinary and yes I run the
stock calipers.
The bias is set to 60 -B 65% front. The soft pedal was determined to be the
front circuit
but using a half dozen different methods to bleed dual circuit brakes I
couldn't get
the slack out of the front master.B Last thursday I bledB the brakes and I had
a great pedal.
It engaged both circuits right from the top of the strokeB but got
progressively worse after
test & tune on friday. No fluid is leaking anywhere but lost almost 50% of my
effective
pedal travel. I also cleared the lines of all my old fluid and put in new (
castrol)B last week.

you may have 2 separate issues, brake & suspension.
Could something in the suspension be causing excess bump-steer?
Possibly too much front brake bias, ie overworking fronts? I assume you
have Girling 16 calipers?

Greetings FoT,
B
This past weekend the RMVR had itbs inaugural race at High Plains
Raceway.
Over the course of three days I absolutely thrashed what started out as
pristine
front rotors. Day one I noticed the car was skittish under heavy
braking, then
my brake pedal got soft. Several attempts to bleed them were made with
no
luck.
During one of those attempts I notice my front tires were heavily worn
on the
inside edge. I checked my front alignment and I went from my standard
1/8b
toe
out to 5/8b toe out. I must have upset the steering rack during my last
engine change.
I use a dual circuit tilton pedal, Porterfield vintage pads and Uncle
Jackbs
spindles,
2.5 degrees negative camber and two Spit clutch masters for both front
& rear
brake circuits.
Is it possible that with the alignment so far out, an eccentric load
was put
on the rotors?
Ibve run three races on these pads including an enduro with no
abnormal wear
issues.
The pads nowB show signs of spider web cracking through out all four
pads.
Has anyone else ever had this experience?
Any advice would be appreciated.
Jim Gray
RMVR # 102
PS This new track is fantastic, if any of you get the chance to come
out and
race with us
you won't regret it.
