Hi, I am working on an early Puma 550 Spyder . It has a CNC pedal cluster installed with hydraulics for the brakes and clutch. I have discs up front and drum in the rear. The unit was probably new in the early 80s but when i added fluid and a pressure bleeder I cant get fluid to the clutch cylinder or the brakes at about 10 psi on the bleeder. I was wondering what the popular set up is currently as far as brands for the hydraulics .I can pull the set up and try to install new seals but was wondering if theres anything better. Thanks.
CNC and Neal pedal assemblies are virtually the same. I believe the two businesses were one once. I believe the brothers separated at some point and we ended up with two brands.
Anyway, Wilwood makes a clutch master that will work. I believe they are 1/8" pipe thread on the out fitting. Check the bore size and match it before ordering, I believe they come in 5/8", 0.70" and 3/4".
VW master cylinders fit in those pedals no problem, if you need to change that. Get a TRW MC, I try to stay away from Chinese stuff, to fit a disc-brake Karmann Ghia.
