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!

Hi , I was wondering if any of you more experienced guys have tryed using the " proportioning " valve from the 944 ( turbo ?? ) setup which was mounted on the master cylinder BEFORE the line or is the thing I am referencing something else entirely??? I've read all about the pitfalls of the Tee fiting , heck I even got some with the same ideaology as others in the replacing with part , haven't done it yet , probably won't as I understand more of what the 914 prop. valve really does , slick as hell those Germans, looking to do 911 M rear , maybe A front or if I get the courage up to refurb the S set I have , like I stated just curious if the 944 part was a possibility .

okay so....get hawk pads for the rear, then adjust rear proportioning valve? i love my brakes, just want them a little more in rear. i havent bought hawk pads for the rear yet, but when i do how many turns would i have to turn incrementally each time to slowly get to where i want to in the rear brakes. I turned a half turn then 3/4 turn OUT and still lock the fronts.......guess i am still WAY over biased in the front since i have correct venting (checked perfect) with stock cheap pads in the rear......
i dont do any racing, or plan on it. Just some spirted driving. Mainly looking for emergency stopping power only when i need it. I dont overwork my brakes on a constant basis, just LOVE knowing that they are perfect when i need them....... This is my STARBUCKS run car or short trip car...no high speed canyon driving.... And wow, i never knew the difference HAWKS pads can make....amazing! |
