Here we have a front brake kit put together for me several years back for my Contemporary by Bill Bassett of Bassett Jaguar.
Six piston calipers, hats, rotors, radial mounts all designed to fit type 1 uprights. I believe Bill had to turn down both rotors dia. to fit my 15 inch Halibrands.
The kit is complete including safety wire.
Not for sale - I just wanted to share info.
Caliper part #-120-6112-RS and 120-6111-RS
Aluminum hats#-AS-8386
Rotors# - 160-12286 and 160-12285
Radial mounts are both FW 6309
Rear brake will need upgraded to match this set up - this is a lot of front brake.
Bill told me that this is the set up he used on a e-type vintage racer.
