I recently bought new rear calipers, redid the front BMW brakes up front and installed HAWK race pads up front. The braking has significantly improved! YES! but now i have one dilema......The front brakes lock up EASILY and the rears never at all..........I wish i could make all them lock up in emergency situations or at least more Braking in the rear.
Did i just significantly make the front brakes better by installing new race pads and BMW brakes? Can i adjust anything with the stock rear system to get more pressure to the back so i dont lock up the front VERY EASILY??? thanks guys i appreciate your help..... Stock 1.7 liter GOING SUBARU 2.5 200 hp N/A soon!! Trying to make everything else PERFECT before i get my third Subaru done.....The braking was lacking on my last conversion...... thanks!

QUOTE You should not need any enhanced cooling such as the AJ setup unless you track the car. One thing to watch out for with high performance pads is squealing. I have a set of KFP race pads on my street car right now that squeal badly at 30mph or less. I have to slightly disagree with Eric on the rear pad clearance. IMO .008" is correct and proper per the factory manual. Except he has BMW calipers now with about 40% more pad up front on the same rotor. I agree however, probably not needed for regular street duty even with the BMW calipers. .008" was the original spec. in the manual but they (Porsche) sent out a TSB revising that number after the manual was printed. All of the Haynes and Clymer folks picked up the .008" as well. Later the factory revised to .004" -or- basically the thickness of a business card vs. two business cards. I doubt there would be much difference as the mechanism in the piston allows for much more travel but, as the pads wear you may eventually have handbrake issues. .008 - .004. Either one is better than where 80% of them are set right now. (IMG:style_emoticons/default/biggrin.gif) |
