I've got a new car from Reno Superformance. It has the newest rear caliper with the incorporated e brake. This is an up grade from the fined rear caliper from 10/2007 which was also a new rear caliper.
My car and others with this caliper hace no stopping power from 70 to 0 mph....NONE...LIKE DEFINITELY NO BRAKES. Talking to Steve at Reno Superformance, he has tested and foud the brakes defective. He just does,nt know why yet Anyone have any ideas on these new Superformance cars???

Why don't you contact Superformance HQ in Irvine, CA (Hillbank Motors)? I'm sure they would have some answers for you, or at least some ideas on how to trouble shoot the condition.

I have spf 2742. It is four months old. I have no idea what you are talking about. Mine stops just fine. Something is out of sync with yours. Take it to someone else and have them look at it. My .02 cents..........

Steve has done everything on my cobra, I would trust him to figure it out and resolve the issue. He's got the experience and the contacts to get it resolved. Post the results since I've been kicking around the idea of going to a different style e-brake.

wanab5150 Check 3 things, First do a manual bleed of the rear system. do it slow and easy put a clear hose on the recovery bottle and watch for bubbles. Do this about 4-5 time Tap on the rear calipers to make sure there is no air in them. Next How where the brake pads broken in??

You are giving a way to break them in with glazing them. If you glaze them you need to sand the pads on a flat surface, same with the rotors. Go out and drive the car do 5-10 medium pedal stops to 0 mph. After the stops, go and cruise and let the rotors and pads cool off, REPEAT this process 3 times. You should have good rear brakes. The other thing is whos pads are on the car. You might have a carbon kevlar compound that needs alot of heat to work properly. If these 2 things don't help you need to go and get pressure gauges for measuring the clamping force of the calipers. I don't know what the correct pressure is for your car, I am guessing 900 to 1,100 lbs for the rear. Dennis O. should know. If pressure are low, on both, the master cylinder is bleeding down internally and will need replacing. Good Luck Rick L.
