Got my new rear brakes in (finally), here's a link to the pics!

mysupragallery.com -> rear brakes

did these during down/rest times while working on replacing HG. pretty easy, drill the bolt holes, shim the rotors, viola, it's done.

At this point is when you notice that the MK4 brake line is too short :eek: . I used a LS430 front caliper hose on the driver's side, still need one on the pass. side (the mk4 line is pulled pretty tight, but will work for now).

Got all the stuff for the front brakes, except for the LS430 caliper bolts (m14 x 1.5 x ~ 100mm is difficult to find at places other than Toyota....), and still have to machine out the mounting bracket.

nice job so you use the MK4 rear brakes and the Lexus LS430 from breaks? and all you have to do is run different lines to the calipers?

Will be using MK4 front rotors, LS430 front calipers on the front. Have to make mounting brackets, as well as machine the hub or rotor. Brake lines should work on the front. The rear brake lines for the MK4 calipers are a different style than the MK3, and the ones that came with the calipers were too short. The Lexus front hose was the same style, but longer, so I used that on the rear.

I didn't. Drilled out the spindle to fit the larger MK4 caliper bracket bolts. For shims, I just used some flat metal that was the proper thickness, cut a few strips, and wedged them in as I put the rotor on. They're a pain to deal with when taking the rotor on/off, but once the rotor's on, works great.

Wzup Lali. The holes match up but they are just a bit too small and need to be opened up. :)

hey Ant

yes i know about that, i had to drill and re tap mine on the NA-T i had, but from the pics it looked like the 5 bolt pattern was drilled twice, but a closer look shows them smaller, i guess different fitment maybe. anyhow i used stock rotors not aftermarket.

i didnt like the hub fitment either because of the play, i didnt want to use any quick fix shim so i ended changing back to stock. i figured it was too much trouble for the little gain. i rather do the fronts and leave the rears the way they are.

How much do u say , u spent on this upgrade and do u want to do it to my car :) . Ill have to check it out one day.
about $825 so far (4 drilled & slot rotors [new],pads,paint,graphix,both sets of calipers[used], & shipping), + whatever it costs to get the front rotors to fit. The adapter bracket for the front calipers I'll make myself most likely, should already have suitable metal stock.
If you get the parts, I'll definately help! Once I get the dimensions, etc. for the front bracket, another set shouldn't be hard to make.


Driving impressions: wow. much more of an improvement than what I expected for just rear brakes. didn't increase firmness of pedal, but when those rear brakes grab, you get stopped in a hurry. For those of you who have pulled a trailer w/good brakes before, that's kinda what it feels like -- an extra set of brakes.
Can't wait to see the difference from the front swap!

man that sounds impressive. i like the sound of this all together.

so youve got TT rear brakes and LS430 rear calipers on LS430 rear caliper brackets and used the FRONT brake lines off the LS430 calipers to reach the rear calipers when mounted on the MA70?

when you said you drilled the spindle, you had to elnarge the inner diameter of the caliper bracket bolt holes where the pass thru the spindle and thread into the brackets?

yes to all of the above, except about the LS430 calipers. They are front calipers, and will use a custom made bracket. I followed Dr.Jonez directions, but when I went to connect the brake lines from the MK4 rears, they were stretched too tight. On the passenger side, I had to remove the clips that hold the hardline in place where the rubber line joins it. The LS430 front lines are just like the MK4 rear lines, but longer (I had some that came with the front calipers ;) ).

BTW, the front brakes are like one of the Night Pager kits, you can see some photos of it on thier website here , and a small write up here . These pictures & my own measurements are what I'm using to make the front caliper brackets.
