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!

Too many variables left out of the mix. The following are my opinions based upon engineered systems: M-Caliper and Boge Strut - Good for stock 914's through 150hp. Replace the P-valve with a T-Fitting -or- replace the 914-4 rear caliper with a 914-6 rear caliper (t-fitting is $9.00 and 914-6 calipers are more like $900) This works for 914-6 applications and basic 911's up to 140hp. S-Caliper/A-Caliper (SC) and Related Strut - Good for stock 914's through 240hp. Replace the P-Valve with a T-Fitting and possibly use a vented rear rotor. Stock rear brakes are marginal at this point. Consider using a rear M-Caliper and a different handbrake assembly. Works for 911S, 911RS and the first 930 Turbo (240hp). Carrera 3.2 and Related Strut - As above but I would definitly use a larger rear and vented rotor. Early 930 (meaning the specific 930 caliper which is noted as the 917-style) - Go with the entire system and find a handbrake alternative. Beyond those... as above for the 930 (917-style). Weight in with your other caliper choices (but he did say 911). I think Mueller has a formula for piston size. That's what I would go with if you wanted to do a mix and match. Gee, sure am glad I never got around to taking THIS clown's advice... (IMG:style_emoticons/default/happy11.gif) pete |
