rear drums to disc conversion ....list all parts needed

[jerry rojas]

list all parts needed of a gts...cuz im gonna go to the junk yard tommorrow....i have a 2000 gt......thanks

[Jun Jun]

I was told all you needed was for a non- abs gt: GTS E- brake assembly, R/L rear calipers, R/L rear rotors and rear brake lines. I got this info from some guy that did the conversion to his gt.:wiggle:

[GTpiMp]

Is this everything that you really need?

I remember someone saying that this was a HUGE project!

What about getting an AEM big brake kit?? Would that do the conversion for you as well?

[Gas-n-Grease]

Yea, i want to do this conversion too. A friend of mine said that we would need a GT-S master cylinder as well. Is that right?

AEM Big Rotor Kits are for the front only.

[Alfy1]

No you dont need a new master cylinder. No you dont need the whole e-brake assembly. It is not that big of a project. All you need is everything in front of the knuckle and a brake hose. The caliper, rotor and e-brake cable and almost everything else is attached to knuckle so you dont have to dissassemble it. I think it is either four or three nuts and bolts holding the knucle in place. It is a simple swap. The hardest part was connecting the e-brake cable up under the car and over the damn heatshields.

When you visit the junkyard you'll be able to see it...

do do it right you also would need the proportioning valve!

[GTpiMp]

Does anyone know where I can find a writeup on this install?

[larryd]

No but when you install it make sure you do a write up ;)

[jerry rojas]

well guys i found a 2002 gts disc rear brakes.....i got everything from the rear like the picture posted by Alfy1....do i need anything else in order to complete my conversion....thanks

I would do one up in a second ... just gotta figure out what I need!

[CelicaBoy230]

I ended up replacing the rear arms + carriers against my will :mad: damn siezed bolts!

yes, the proportion valve. located behind the heat shield by the manifold

[celica604]

Actually the proportioning valve only needs to be changed on an non-ABS. The ABS version doesn't use one but rather uses ABS actuators which are the same on both the GT and GTS. I've had the parts sitting in my basement for years to do this just never got around to doing it. Just finished painting the calipers yesterday and reassembled one caliper and the other on will be reassemmbled today. I'm probably going to install it this weekend and I'll take pics and do a write up. Just need to pick up some new brake hoses, a dust boot that I lost, torque wrench, flare nut wrench. The goal is to have it finished by Sunday morning.

[fubarlphie]

the junkyard i talked to said i also need the rear knuckle, is that true?

[spidalegz_2002]

hmm..interesting. i have the AEM big brake kit on my front, and want to see this done so i can do the back also.

[celica604]

The part# on the rear knuckles are different on the GT and GTS. After close inspection they're pretty much the same the GT just has a hole to mount a bracket for the the brake line (diffence may be more apparent when removed). I have the GTS one so will be using it.

[jerry rojas]

i have 2000 gt no ABS......I ONLY GOT the gts e-brake assembly, rear calipers, brake lines, rotors and whole rear assembly .....what else do i need..all the parts were taken off a 2002 gts with ABS........IM ASKING BECAUSE people say i need the rear arms or the proportioning valve......i wanna make sure before i do this...help me out

[Jun Jun]

The guy that I know that done it to his gt told me all you needed was what I've listed above. From what I was told you do not need e- brake cables, knuckle, hub, and brake booster.

[agular9]

good info, now we just need someone to make a write up on the install and a list of parts needed instead of having to search through this whole thread.

[Mike Morris]

Be advised when you convert to disks in the rear you will gain some weight.
I have seen Celicas on the dyno LOOSE power with big brake kits on the front. But if its needed its a good mod.

[100to5]

If you just look at a gts (non abs) you will see the rear brake assembly is on the car by three bolts. All you need is that whole assembly and its a direct replacement of the gt rear drums. Make sure you have the whole ebrake line with the metal knob at the end to hook it to the connecting point above the piping under the car, along with the brake fluid lines and calipers. http://www.tcforum.com/forum/images/upload/Members%20Rides/NeSyO03/720.jpg

[jerry rojas]

WHAT IF THE rear brakes came off a gts with ABS...DO I JUST IGNORE the connector behind the whole assembly

[celica604]

Crap looks like I have to wait a week or 2 before i can do the write up as my local Toyota dealer wants $90 for a pair of brake hoses.

I dont think it is that big of a difference

Did they ask you for a vin? The part number for the 00-01 is different from 02-03, I think. I forgot which year they changed them. If you get a chance just get braided steel hoses. Be very careful when you remove the stock drum hoses. I striped my bolt with a flared wrench. I have not fixed them til this very day.

I also do not have a proportioning valve. Does anyone have picture of it?

They make rear also. castrogtstoyo has em. ;)

Hmmmm.....I wonder how much it is? *EDIT* AEM Big Brake kit for the rear will only work for a GTS supposedly. However, you would think if you could take the brakes off of a GTS and put them on a GT then you should still boe able to use the AEM rear big brake kit. All you would need to do is get the certain parts you needed plus the AEM kit. On the other hand the stock rear brakes off of a GTS would be just fine for me, especially since the front is what does like 85% of the braking anyways. I just want disc brakes in the back.

does anyone know?

I am going to be hitting the junkyards Monday ...

[GTpiMp]

Can anyone give me a ballpark price on this stuff?

I called a few places today and it seems as though $200 CDN ($150USD) is the going rate for each side.

Does that sound right??

[GTpiMp]

Actually my mistake ... $250CDN ($175USD) for each side.

This includes everything except the brake lines and calipers. The car had 34K on it.

I have read that the proportioning valve is not any different if you have a NON ABS version ... which I do.

Is this correcT?

Which junk yards did you call? I'm in the GTA area but Kingston is only a 2.5 hour drive away...

if it doesn't come with the calipers where were you planning on getting them from?

Holy Shiet you have got to be kidding. For that price I can almost buy a new rear disc brake conversion. Forget that. I am not paying $175 for some used crap on each side. That would be $350 for the rear brakes and I think I amight be able to swing a rear disc brake conversion fora little over $400!

[GTpiMp]

I didn't call any in the GTA ... I used www.car-part.com and found a place in Calgary.

No idea where I was gonna get the calipers from ... hadn't got that far. In the end I was lookin at $600CDN after shipping and taxes for the two rear assemblies ... so I left it at that.

Any idea where I can find em in GTA? I have friends up there who come down every weknd.

[Alfy1]

I got both of my sides for about $300, excluding the brake lines...I got it of ebay though.

[GTpiMp]

So what all did you need to buy?

Was the install pretty simple?

[Blue13]

What exactly do you need?!
I really want to do this...I called Toyota and he told me there was too much sutff for him to list over the phone...I said it doesn't seem liek much from what I have read. He told me that if I were to buy it new it would be around $4000...! I told him he's nuts. The he said that I'd have to change everything including some suspention parts. Is he crazy?

[GT-Esless]

Um...How can you "loose power"? a tick slower sounds right, but you're not doing anything to the engine. it will still put out 130hp or whatever these cars put out. ex. if you put an extra 100lbs in the car do you go slower because you have extra weight or because you "loose" hp?

[GT-Esless]

Chances are that the dealer is crazy...He's probably listing every single part (some which you already have on the car) in order to get a bigger sale.

[T3HKMAN]

The dealer is crazy you need exactly what is in the picture that 100to5 posted above.
As far as a proportioning valve goes it doesn't seem necessary if you get a rear disc conversion that has ABS and your GT doesn't have ABS.

Rear disc brake conversion done with black zinc plated cross drilled and slotted rotors from R1Concepts (http://www.r1concepts.com) and teflon coated stainless steel brake lines.

[ericismyname]

so the entire disc conversion weighs more then the entire drum setup?

[TRD-CELICA-GT02]

Has anyone who responded in this post, actually done the swap? I bought parts about a year ago for the rear, but since I'm no mechanic I'm not sure if it's complete. I'll post pictures of the parts when I bust it out of storage and could someone help me see if I have everything? I'll try to have pics tomorrow or something. I think all I need are brake lines.

Is that true that we don't need the rear knuckles? Any confirmation would help.

[ryanbbored]

this is all you need. me and my friend swapped the rear disks assembly about a month ago. the only hard part was plugging back the ebrake lines. you need to go through the heat sheild. it was a pain. pretty much just replace that whole assembly and bleed the brakes.

some problems when i installed the rear disk brakes was that now i notice when i step on the brake pedal i can hear the calipers squeaking. you can hear it clamping. also my back right squeaks when i go on a speed bump or a angled driveway.

Did you notice a weight difference in between the drum vs disc set up?

[T3HKMAN]

Did the swap too as it states in my previous post, I can't notice any real difference in weight either but I didn't bother to weight the assemblys when I took them off. You maybe talking about a 5+/- pound difference per side IMO.

Just do it. ;)

[ryanbbored]

Did you notice a weight difference in between the drum vs disc set up?

when i compared the drums to the disk, disks felt a little heavier. i dont feel any weight difference when im driving.

Does few pounds of weight really bothers you? :rolleyes:

[LowcarbonBLue]

Does few pounds of weight really bothers you? :rolleyes:

^^yeah really, i rather have a little bit of extra weight then to have the ugly drums in the back to be replaced with nice disc brakes.

[TRD-CELICA-GT02]

Exactly....plus it's only a few pounds. I doubt you'd notice anything other then the apperance factor, unless you have a weighing scale built into your brain/body to feel weight differences. :chuckles:

[ericismyname]

I was just asking, is that grounds for attempting to critisize me?

[T3HKMAN]

Well my post wasn't an attempt to criticize just inform/help and I agree with you, Eric that there is far too much sniping on these boards. The mod is worth it, IMO.

[ericismyname]

Well since the weight is around the same, why doesnt someone post about the difference in braking?

[LowcarbonBLue]

Well since the weight is around the same, why doesnt someone post about the difference in braking?

umm...there's not really a big difference. Like i said, most people who do this, is to lose the ugly look of the drums. 80% of your braking is from the front. I highly doubt there is a big difference in feeling.

[T3HKMAN]

Well there is a difference in feel to me but remember I pretty much upgraded everything when I did the swap, I'm pretty sure I brake better than a stock GT-S now.

[harv_08]

anyone who has done the swap, can you post a write up with pictures or anything? im looking to do this myself, about how much will it cost to get the disc brakes from the junkyard?

[LowcarbonBLue]

look in the installs part of this site. There is a nice write up. FYI.

[GangstaCelicaGT93079]

I don't know if this was said already but they have a kit to do this as well :cool:

[fievel28]

thanks lowcarbonblue.

and gansta that set is pretty expensive, plus you have to do their front setup too.
