rear disc brake conversion - Toyota Nation Forum : Toyota Car and Truck Forums

bigsexypanda · 01-28-2012, 08:56 PM

So, I'm really interested in converting my cars drum brakes to disc and I was wondering what is even possible to replace it with, in terms of usability and availability of parts and things like that. I'm not looking to make my car into a high performance machine, just looking to make some basic upgrades to my car and make it an awesome daily driver to last me even more then it already had. I was reading that I would have to get it all off the GTS model through searching, but I was wondering if that's the only one. And if so, I would basically have to replace the whole assembly and lines and master cylinder and everything?

i did this on my sr5 with new

calipers,disk,pads,brakecable, and lines.

list.
gts brake lines
both rear caliper,pad,disk. just buy a new caliper or rebuilt it if you want, new pads and disk aswell
rear hubs / uprights
trailing arm or you can grind it to fit
both handbrake cable

you dont need the MCylinder your sr5 one is fine

exhuast pipe is on the way and heatshild to get to the handcables

The exhaust and heatshield is in the way for swapping the handbrake calbes.

The rear discs from an GTS may not be the best way and certainly not the only way but it sure is the easiest way.
I myself are in the proces of fitting the ST205 rear (and also front) brakes abut in my case this requires swapping to 5 lug hubs as well. Overkill? Yeah probably.

Check out this topic for some more info: http://web.archive.org/web/200806032...s.com/main.htm

SX/GTi/GTS/GTZ/GT all have the same rear disc setup so don't worry about that.

ohh and before i put the agx insert on the gts strut casing, i try'd it on

the st184 front strut casing and it fiitted. i save the casing and cut the

brackets from the old sr5 rears and weld it on the st184 casing if i have

time but one day i was looking for it and found out my granma throw it away

I was wondering what places you would recommend looking for these kinds of parts.

I honestly don't know as I don't live in the USA. I got myself a corolla GTi and swapped the rear brakes & engine and then sold it again as an XLi. But you could try the junkyard / ebay / yahoo! or something similar.

In my opinion, you stand to gain more improvement with a larger front disk, than from a rear disk swap, and it will be a bit easier. You can get larger front brakes from the '90-91 GT-S or the '93-98 sedans.
Check out the two links below for front brake upgrades:

90-91 GT-S Brake upgrade

AE92 Front Brake Upgrade

You do know that there ios a search feature on the front page, right?

That is why it is important that we "Title" our threads clearly with the subject of the post, so searchers can know what the content is.

bigsexypanda · 02-03-2012, 04:02 AM

Trust me, I've been on enough forums to hear enough people say use the search function. Well, just like you were saying a lot of times the titles not right and I've searched plenty.

you live in cali. start with a local pick your part. you can take the whole rear assembly from a GTS if you can find it. the crossmember unbolts with i think 6 or 8 bolts from the bottom of the body. and then it's the sway bar, the strut mounts and the hoses and brake lines. the arms will bolt in. if you take it with the arms and all it'll make it easier.
