91 GTS Caliper options

[RED91SR5]

I have to replace all the calipers on my 91 GTS but I'm only finding few and also very expensive replacements so far.

Is there any other years or toyota models that are more comon that fit this year of car?

Aftermarket options?

front calipers aren't very expensive.

The AE101 Corolla calipers bolt straight up to the AE92 hub.

You just have to remove the dustshield on the back since the AE101 brakes are bigger (138mm for most AE92's and 156mm diameter for the AE101's)

Better stopping power aswell and more common if you ever need more (or aftermarket) parts.
I've got this set-up on my AE92 for several years now and I was very pleased with it

I am running the AE101 calipers, rotors, hubs and brake shields on my '89 GTS.
Really makes for more progressive and better braking.

AE101 calipers bolt right to AE92 hubs?? why did you use the AE101 hub donald?

My objective was to have the larger diameter rotor and the caliper.

The AE101 hub (the part that the rotor sits on with the wheel studs) is slightly thicker than that of the AE92.
The AE101 rotor will rub against the steering knuckle with the AE92 hub. It is deeper in the back, (hat section).

The AE101 steering knuckle won't fit the AE92 lower ball joint without machineing down the lower lug. It is thicker than the AE92's.
The AE101 lower ball joint won't fit the the AE92 lower control arm.

The dust shields have the same bolt hole pattern.

The bearings are the same part number for both cars, so I pressed the AE101 hub into new bearings, and into the AE92 steering knuckle.


What you need:
AE101 hub, rotor, caliper, caliper bracket and dust shield.
All that assembles onto the AE92 steering knuckle with no further modifications.

AE92 Front Brake Upgrade

Not true. My 91 GTS calipers and mounting brackets are bigger than the ones from my 89 GTS. Part numbers are different too.


I checked Rockauto, I've have bought from them before and like there service, but the calipers were going to be around $600~$700 Canadian after all the shipping extras. I might have gotten some back on the core charge but the cost to ship them back would probably be to expensive.

He never said the brackets are the same. The caliper part number is the same. I've checked this many times on rockauto and other sites. Of course the part number for the caliper WITH BRACKET will be different for the 90-91 GTS vs. all others but for just the caliper without the bracket, they are the same.

Ok, I just looked and it appears A1 Cardone has a different number for the two but three other companies have the same number for both.

All these calipers are without the bracket and are listed under a 91 DX and 91 GTS.

I just want to clear something up here. The caliper bracket bolts to the steering knuckle, not the hub.

The photo below is of the AE101 hub compared to a Paseo hub. The Paseo hub is about the same size as the AE92 hub. The one on the left is the Paseo, and it still has the bearing inner race attached. You can see the difference in flange thickness(where the wheel studs attach). That is why I needed to use the AE101 hub on the AE92 steering knuckle for the AE101 rotor to fit and not rub against the knuckle

The difference is only a few mm, but just enough to cause a problem.

I'm assuming you meant 238mm and 256mm respectively.

I'm thinking this "upgrade" would not make sense since the 91GTS already has the 10.16in (258mm) brakes stock.

Indeed, that was what I meant

Some of the later AE92's do have the AE101 calipers, but was unsure if the TS already had them. And If so...he asked what he could use from other models, so his question remains answerd

About the rotor not fitting the AE92 hub because of the steering knuckle etc...I havn't had any problems with it?
I took the AE101 rotor and caliper and it fitted straight on the AE92 hub. I only removed the dust shield and I was ready to go.

I don't believe there is a difference between the Euro en US spec hubs is there?

Hmm.... that's funny....

I have a 1990 geo prizm gsi Hub, a 1990 corolla SR5 rotor, caliper and bracket all bolted together. When I took the hub off of the strut (yes, I have 100% of the ae92 geo prizm gsi suspension floating around the garage) I compared the caliper, bracket, pads, hub, and rotor.....

all the same.

The only way that mine would be different is if the 1 previous owner of my corolla (which oddly enough was the President of REI's wife...) is if they had gts parts put on... considering the car was 100% stock when I got it, I have doubts.

All these calipers are without the bracket and are listed under a 91 DX and 91 GTS.

I should clarify:

For whatever reason some 91 GTS "calipers" are about a quarter inch wider in the pad area, so even though the calper pistion area etc are the same as 89 GTS, the 89 calipers will not physically fit over the pads and mounting bracket for the 91. Yes the mounting bracket is longer on the 91 as well.

I'm not saying this is the way it is but this is the difference on my old 89 and 91 calipers 'and' the new ones I finally just grabbed over the weekend. They first gave me the wrong ones, I should note that I spent a couple hours with a parts guy tracking down the right sized 91 GTS calipers and mounting bracket because their computer, like rockauto, have wrong parts numbers listed! He made a note of this for future reference but since there are so few of these models left I doubt it's going to be an issue for them.

Not saying you were wrong, maybe mine are just later 91 that some of these guys are saying might have the AE101 stuff, but if thats the case I wished all the parts places would have a listing for the time of year that they changed to the bigger brakes and have saved me the headaches of figureing it out the hard way.
