<VV> Vendors disk brake kits

[Rick & Janet Norris]

I first installed a front disc brake kit from Clarks on my 66 V8 Vair. I 
encountered a problem with the caliper hitting the lower edges of the upper 
A arm when the wheel was turned far left or right. The car is lowered. I 
changed to a Bob Coffin kit. It uses a smaller caliper body ( but still with 
the same size piston as Clarks which is a larger caliper from an S-10 truck) 
and is clocked more toward the front giving more clearance between the A arm 
and caliper. I also opted for the aluminum bracket. Steel was available. 
Both kits required the wheel hub outside diameter to be reduced , easily 
done on a brake lathe to fit inside the disc hat area and a spacer which 
requires longer wheel lug studs. Some time later (several years) I did 
receive a notice from Clarks warning about the possible problem and a 
solution. In my opinion the fix would work but it was not something the 
average guy would be equipped to do as it required cutting and welding on 
the A arm.
As with any disc/drum set up you really need a proportioning valve in the 
system as the hydraulic pressure to squeeze the disc is a lot more than the 
pressure to activate the drum. I also use a 7" power booster which is highly 
recommended. My disc/front drums/rear brake system works very well. I have 
tested them at several track events with no problems. Pictures at
