I am still having issues with brakes on the race car.
car is a late model circle track asphalt car.
It has dual MC's and a NEAL brake pedal
front calipers are HOWE and rears are wildwood. all have been removed and cleaned
MC's are the rectangle type. my pressure bleeder does not mount to them so I just ordered an adapter to fit them, problem may be the MC's are too close together to use it. I may have to unbolt one at a time.
problems start with
the MC's are mounted LOWER than the calipers.
problems:
1 cant get the system bled
2 I think the fluid may drain back since calipers are higher
3 brake bias.
4 seems like poor fluid flow to the rear's
1. last attempt at bleeding my son pumped while my wife sucked.(had to put that one out there for rawknees). I had my vacuum bleeder connected to the calipers although not a great seal at the nipple. the pedal seemed hard, best its been, after doing this. but on to problem 2
2. I got in it the other day and drove it down the street. pedal seemed spongy again, not as hard as right after bleeding. just read today about drain back and found this.

4. seems like the fluid flow to the rear is low. especially the right rear. the left rear did lock up on short test drive, not sure about RR.
it does have very old SS braided brake lines. not sure if they go bad inside like the rubber ones do
3. brake bias.
it does have the rod that goes between the to MC's BUT!! the center pivot does not move like it does on the wildwood so I am not sure of how the bias is adjusted other than perhaps rod length of each MC.
