When I first got my roadster the brakes were terrible! I pulled out of the
Previous Owners Driveway and across three lanes of traffic! I first
attributed this to the fact that they were non-assisted, But that didn't
hold up for long. I took it to my first Doheny show, and had Gary Cohan
drive it. His comment was "What's up with your brakes?". Changed pads to
even more problems. Now the pistons were in new possitions, obviously where
there was plenty of pitting. So now I had leaking, crummy brakes instead of
just crummy brakes. Four new pistons and Axxis Metal Masters and WOW Now
those are brakes. Outstanding! Now I can realize why these units were used
on the "E" type Jags and the 3800lb Jensen Interceptors. Not much of a
challenge dragging down our 2100lb cars! I looked up these Porterfield R4S's
that Tom spoke of and at $99.00 a set I don't know just how much better they
can be.

Fred,
The Stock brakes do work great! Trick is making sure everything is up
to par and good.
I would recommend trying out a set of R4S (hope that is the number,
I keep messing it up). Basically some super nice pads & shoes for a
stock braking system on a roadster.
I have mentioned in the past, but when ever someone would tell me
how "bad" the roadster brakes were, I would take them for a quick
drive. I'd warn them I was about to "STOP QUICKLY" and hit the brakes.
Usually made a believer out of them once they realized I was using stock
brakes!
The vented rotor & four pot calipers are overkill for a street / autox
vehicle. You gain a lot of rotating weight (rotor) and unsprung weight
(calipers) with that set up. Keep the weight down, but the braking
power up with the competition brake pads & shoes (S is for Street, so
they will work when cold... important on a street driven vehicle!).
I've been going through the same thing with electric vehicle conversions,
but when you take a 2000 pound vehicle and make it into a 2800 pound
vehicle, you really need the beefier brakes!
Cheers,
Tom Walter
Austin, TX.
