Glad to see this come out of the "what did you do to your Camry today" thread. If we get some completed upgrades, this would be good for the sticky info thread at the top of this section of the forum.

Oh, and rear disk swap information here would be good too... for those FWD 4-cylinder guys.

Also note that the front of the Alltracs are the same as the FWD's - but the rear disc parts are different.

If you give a list of All-Trac specific parts I'll add them, or any bolt on brake parts. I'll add the the rear disc upgrade list when I get a chance.

 

Excellent thread!

For those with a Gen3,4 or 5, there's another thread here.

Speaking of the back plate, you usually have to bend it so it can clear the now larger brake rotor. Is there not a way to just swap out the brake back plateout to the larger one or is there something else that won't work/can't do that?

Swapping the front backplate means pressing out the hub.

 

Hmm... Good to know. LS calipers would be a big upgrade over the Camry stuff. The 93-94 used twin pot calipers but I don't recall the conversion differences, I'll do some digging and see what I can find.

Edit:

If I'm reading this right, everything up to 2000 used the same mounting pattern... So we could possibly use the Gen 2 LS 4-pot calipers, or Supra TT calipers if space is a concern.

Is there a reason the 91-92 work but 93-94 don't?

The newer calipers have a different bolt spacing for starters.

 

Hmm... Could've sworn the 93-94 was a bolt in deal for the earlier LS, but that makes sense. I'll see if I can find that old thread about LS brake upgrades. Might be some relevant info.

 

I was in the LS market some months back, knew I was missing something. Are the LS400 calipers you mentioned single piston or dual piston? In 1990 they used a single piston caliper but moved to dual piston in 91, then to larger dual pistons in 93. I think this is where my confusion is coming from. That said, if the Celica bracket will support the single piston LS caliper, it should be fairly simple to adapt a dual piston caliper/bracket. I'll play around next time I'm in the salvage yard to confirm.

Dual. The '91-92 LS caliper will fit the Celica bracket I've listed/linked to it under the Calipers heading. I'll add more if/when people discover they bolt up.

 

If you're going to rebuild the calipers yourself, don't too much work and you won't save much either. That's assuming the remans like Centric are good parts. They did clean up nice at least.

 

I will likely go for new calipers when I go for the final install on my own vehicle, but salvage parts are perfectly adequate for test fitting things... We'll be in Albuquerque next month, so I'll have an answer fairly soon.

 

Celica brackets came in did some test fitting, there may be a problem. The caliper touches the bracket when the slide pins are fully compressed, mounted into the ES bracket there is about 5mm of clearance. Celica bracket on top.

I measured the brackets and got about a 5mm difference in these areas, ignore the geometric distortion of the camera

So this may not work the caliper as it floats might hit the bracket and you won't have proper brakes or no brakes. I suppose a person could take down 5mm of material from the caliper but that type of modification is sketchy. I could mount a caliper and do a test drive, could be dangerous.

Don't know what to do going forward .

 

I didn't have that issue, although they were close to touching. Even with the thicker Celica caliper there is room. Maybe after installing the pads there will be enough distance taken up that that won't be an issue for you.

 

You are using all gen6 Celica parts right? If so you obviously won't have this problem the parts are designed for each other. The mix/match is where things are going awry.

 

That's without pads installed though right?

Except that the Celica rotors start out more than three millimeters thicker than the ABS Camry rotors. So it really shouldn't be a problem for your setup.

 

The pads and rotor don't matter the caliper is going to float in its natural position regardless. The outer edge of the caliper is hitting the bracket, doesn't do that when the ES caliper and bracket are paired together. That 5mm might not matter or it might be a show stopper. Only way to find out is install the setup and drive, to do that I won't be using a good set of calipers and pads.

 

Are these brackets cast iron or steel? If steel, it would be a fairly trivial procedure to remove that center section and add a new one that clears.

I did this when I upgraded the front brakes of my 7th gen corolla using an ST-205 celica SS II or was it SS III super strut front discs, calipers and caliper brackets. Even before I decided to change the brakes, I read up on the potential problems associated with install celica discs on a corolla front hub since the corolla disc has a 47mm height and the celica disc is 49mm plus the caliper bracket has a different offset so when I installed the disc and the caliper bracket on the front hub, the bracket itself was closer to one side of the disc by about 1+mm and I wanted it to absolutely centered so I found that raised section on the caliper bracket bolt holes and ground it down so it moved the bracket itself about 1+mm inwards (or was it outwards?) I think and centered the disc on the bracket when I tightened the caliper bracket bolts.

Its very important that every parts is installed the way the OEM was installed so that there is no problem even when the brake pads become thin with use..... If one side of the caliper bracket has a bigger clearance than the other side, a very thin brake pad may suddenly escape from the caliper bracket when you press the brake pedal and cause havoc and a potential accident with your car while on the road.....

This is my concern, on a fresh set of pads the brakes may seem to work fine but as they wear the caliper might move to the point where the pad twists or even come out.

It might be possible to modify the ES bracket it would involve taking off material towards the inside (where it bolts to the knuckle) then drilling and tapping two holes. But such a thing requires precision not sure I could do it properly using a drill press and a bench grinder.

I used a rotary tool and a cutting disc to evenly remove the material from that raised section..... took a while but it was fairly even when I finished it.

 

Update: figured out what's up with the later LS calipers. They're a true mono-block design, they do not use a bracket. This is why they're bolt-on for the earlier LS400, they bolt straight to the knuckle. Shame, but they are just not quite right for the Camry knuckle.
