"bolt on" brake conversion options for FWD/4WD 5 x 100 stud pattern	Mon, 11 October 2004 06:17

Brake Upgrades for FWD/4WD with 5x100 stud pattern These started out as my original front brakes, & cause Im more of a twisty road person, than straight line speed, I didnt think theyd be adequate. These are a single piston floating calliper. First upgrade was to a set of ST185 Jap spec front callipers. I didnt need to change discs, which Ive been told is the same for all Celicas upto ST20x models, Camrys, etc The only mod needed was to grind away some of the brake backing plate to clear the calliper. The brake lines bolts straight up with old fittings & hub-to-calliper bolts are identical. Only problems is that you cant buy these brake pads from Toyota, as the Aussie ST185 GT4 had a single piston calliper. I took the old pads to a brake shop & they were able to match it. Eg Bendix makes pads that suit. After fitting these I found I had a brake balance problem (not helped that my rear struts were stuffed) caused by locking the rear drums. So I converted these to discs (there is another article on doing this) Next step was to really get serious. I managed to locate a set of ST205 discs & callipers off a half cut that wouldnt fit the donor car. (The discs are TRD, not Toyota items and came pre-slotted) As you can see they are much bigger than either of the other callipers Id used. The brake pads are also larger. .... Single piston ........... Twin Piston ............... Four Piston .......... ST16x, ST18x ........................... ST205 ............ST205 ..................................ST16x, ST18x There are a couple of traps Ive discovered after getting these brakes which do not make them a straight bolt on. These are all caused by the calliper mounting position. The single & twin piston callipers are mounted on the wheel side of the hub, meaning the hub is simply drilled while the calliper is tapped.
