Fastrotor Posted April 11, 2008 Share Posted April 11, 2008 Hi Guys, Ok, this is to the Auto guys, although just as applicable to the manuals as well. I had the rear in the air the other day so i could spin up the tyres while i was gathering data scoping inputs to the auto computer, and i noticed to my horror that i could stall up on the handbrake alone about 3 times more than just using the brake pedal !! I mainly sprint race the car, it doesnt get driven on the road alot these days , so it sits a month at a time between rounds. The car has slotted dba rotors, machined with EBC reds front and Greens on rear bout a year ago. I've had no obvious dramas while racing with the brakes. The only thing i did notice is that when over doing the drags for a run, i simply couldn't get it to stall as good as i used to, even with the new 3500 converter ! (over the previous 2800). Any one had a similar problem with this ? Im guessing either air in the line or a seized caliper possibly. Possible pad contamination long shot. I'll be ripping the wheels off tomorrow for a better look , just thought id post up to see if someone has seen similar, and once i fix it , its info for someone further down the track.

BHDave Posted April 11, 2008 Share Posted April 11, 2008 so you have a skyline? If so I guess you haven't worked out you have a drum handbrake built into the hat of the rear rotors yet? The hand brake and rear brakes are 2 completely separate systems Link to comment https://www.sau.com.au/forums/topic/214476-handbrake-stronger-than-rears/#findComment-3788663 Share on other sites More sharing options...
Mr. Keets Posted April 11, 2008 Share Posted April 11, 2008 I would have thought stalling it on the front brakes using a line lock would have been the way to go Link to comment https://www.sau.com.au/forums/topic/214476-handbrake-stronger-than-rears/#findComment-3789007 Share on other sites More sharing options...

The hand brake and rear brakes are 2 completely separate systems Yes sorry its an S1 R33 Sedan. Yes well aware the hbrake is drum. Hence i find it strange that its got about 3 times more holding power that the disc brakes, and hence my problem and why i was checking to see if someone else had come across similar.

I'll post the results for posterity when someone else is looking possibly later on.
