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!

Kyle,
Do you have a firm pedal issue? If so I would look to the shut-off valve and measures to make sure air is out of it. Regarding the locking - Dave Sprinkle had this same problem and his pads weren't bedded in yet. For his street car I recommended the Ceramic pads which he eventually thought were "good" (once they bedded) but not great. He ended up not liking them because they were very dusty. I have the same situation on my wife's Mercedes wagon. I "really" liked the ceramics but they are dusty. I think they're the best in-expensive pad solution at around $35.00 Back on target, you should have great pads, I would be concerned that they've yet to bed in as R4-S's are one of the best pads out there. The only other person I heard of with a similar problem was Dave and he reported back as mentioned above. Regarding the bench bleed and the pedal. You mention bleeding so I mention pedal. I don't think the master cylinder would be an issue. I have a theory on 914 brake bleeding that I want to look into this weekend. If I'm correct and I can come up with a solution this could solve the spongey pedal thing. It involves the shut-off valve. Work on getting the rears bled and bed in the pads and you should be good to go. |
