lex4me Posted August 25, 2004 Share Posted August 25, 2004 I am getting quite tired of warping rotors on my 91LS and thinking about upgrading to the somewhat larger 93-94 brakes in hopes of at least minimizing the issues (I already have 16" wheels from a 99GS on and can live with never mounting my 15" 91 OEM wheels again). I read somewhere (possibly Lextreme) that to upgrade the front brakes you need new rotors (duh), brake pads, calipers, and master cylinder. Some questions: 1. Why is a new master cylinder required? 2. Wouldn't I also need a new caliper bracket? If so, has anyone had luck getting these brackets from somewhere other than the dealer (like a salvage yard)? Thanks guys! Quote Link to comment Share on other sites More sharing options...
jzz30 Posted August 26, 2004 Share Posted August 26, 2004 well bigger capacity brakes need bigger capacity or a master cylinder that can push more fluid. and you dont need a bracket because the calipers have the offset casted in to the caliper meaning the mounting bracket is one with the caliper.

wwest Posted August 26, 2004 Share Posted August 26, 2004 Don't forget wheel clearance.......! Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted August 26, 2004 Share Posted August 26, 2004 actually you don't need to upgrade your master cylinder, since you already have disc brakes. your master cylinder will move enough fluid to work what you are going to up grade to, unless you are going to be putting some 16" brembo's or wilwood brakes. chances are that your current brakes pads are too hard for what you are using them for or you have your foot on the brake all the time.

GRAND_LS 4 Posted August 27, 2004 Share Posted August 27, 2004 Just do a Gen II break conversion, with 4 piston calipers, it’s a big difference. Quote Link to comment Share on other sites More sharing options...
lex4me Posted August 27, 2004 Author Share Posted August 27, 2004 Doing a Gen II brake conversion is exactly what I had wanted to do, but I can't seem to find a writeup that talks about the exact components that would need to be replaced. Can someone point me in the right direction? I do not ride the brakes, BTW, and use ceramic pads from O'Reilly's. B) Quote Link to comment Share on other sites More sharing options...

dole2000 Posted August 28, 2004 Share Posted August 28, 2004 I have a 91. I hated the braking. I got slotted and drilled bremble rotors and ceramic pads and now I am happy with the braking. Cost me under $400. Quote Link to comment Share on other sites More sharing options...
