Cressida Big Brake Upgrade
« on: Mar 29, 2011, 08:09:57 pm »

This upgrade is a direct bolt-on using the calipers, mounting brackets and rotors off of '87-'88 Cressidas to net bigger in diameter (+ 9/16" / .5625" / 14.28mm) and width (.078" / 2mm) rotors (which is mass and a factor in braking ability) for 3rd gen Celicas/Mk II Supras, and in my case, an '81 Corona that had been upgraded to a mix 'n match of 3rd gen Celica/Mk II Supra front end pieces (among others). There are Brembo blank replacement rotors and performance pads such as KVR available too.

Before digging into this and for a little more insight into the 3rd gen/Mk II brakes, see the write up "Front Brake Job". It goes into more detail of the brakes themselves, and I couldn't see duplicating relevant existing info.

One of our local yards had just what I needed:

Make   Model   Year   Row   Date On Yard
Toyota   Cressida   87   0039   03/15/2011

It had only been there for five days when I got there, so was unmolested.

I must also thank Zoomy for coming along and taking pics, offering her $.02, handing me tools, and holding the umbrella! I did pay her way in and bought her dinner though.

Here's the donor (the car, not me):


Looks good so far


Ehh, a little rough:


Well, molding and a couple dings - why would someone let it end up here?


Yup that’s the right year range! I wish the ID tag on the firewall had been more accessible.


Looks like a perfectly good 5M-GE to me


AFM anyone?

Okay, now to work. I started with the left side since the wheel was already removed, but will be switching side-to-side to include all of the steps.

Pull the hub cap off. This may be more difficult than it looks here, like needing a screw(chisel) to break it loose.


Pull the cotter pin out – if you’re a cheapskate and you’re careful, you can re-use it.


Pull the castle lock off and remove the axle (spindle) nut – then put the cap back on to keep the bearing in place when you take the whole thing.


With pliers of some sort, remove the brake line clips from the strut and chassis at the hard line, then cut the hard line, open up the bracket at the strut and pull the lines loose.


Removing the caliper bracket - pull the two 17mm headed bolts…


they might be tight and need a push


but should come out quite easily


then you can simply pull the whole assembly off of the spindle


Zoomy and I were both quite surprised to find purple (silicone) grease in the wheel bearings! Somebody had done good work.


I then re-installed the nut and castle lock.


From there, I thought I’d take the M/C (mine was leaking) and the booster (it is a Cressida),


but ran into multiple problems. In a nutshell, it was a major PITA to get the nuts off of the booster under the dash –


The (power) seat  was all of the way forward


There is the closest stud – just above that bolt


It’s a tight fit, and there are sharp corners up there


Tut tut – looks like rain!


Good thing Zoomy brought the umbrella!


It turns out that the booster can’t slip out w/o jacking up the engine a bit because it hits the intake manifold, and of course, once I got the M/C loose, it was leaking too.
I did take the proportioning valve though, as the Corona will get a Mk I Supra disc brake diff shortly.

Measuring Cressida rotor


Cressida rotor diameter 272mm…


…which is 10.71 inches


Measuring 3rd gen/MK II rotor


3rd gen/MK II rotor diameter 258mm…


…which is 10.18 inches


Cressida minimum rotor thickness 21mm


3rd gen/MK II minimum rotor thickness 19mm



For those curious about cost - after a 15% “Spring Break” discount, I was charged $13.17 per caliper (no charge for the four rubber lines or pads :) ), and $9.77 for each "brake rotor w/o hub" ( :huh: :) ). The grand total was $45.88, not including the $3.69 "Environmental Fee", $2.99 x 4 core charges, or the $2 admission fee (x2).
I did not take the backing plates off of the Cressida (for an additional $6.99 each), I just bent mine back a bit.

It is said that material must be ground off of the caliper to clear 14” (GT-S/Supra) wheels. I did not install new brake pads yet, and the calipers cleared my Enkies. I do not know if they will clear with new pads or not, so will update if I do.

I should also go over installation, and include doing a proper brake job, but basically it is the reverse of disassembly - or (again) go to the write up "Front Brake Job" (which isn't quite perfect in my eyes). Make sure the calipers slide smoothly on the mounting brackets…


Again, check caliper to wheel clearance before assuming it is good and messing up a wheel and/or caliper!

I have not taken this out for an abusive drive yet to verify any improvement, but then again, I never smoked the old brakes. It does definitely give me more confidence though, knowing they are even better than my last upgrade!

excellent job Bob!!! Please let us know how much better they are on the sled... so the cressy spindles are the same as the 3rd gen spindles? why did you not grab the rear end while you were at it? I know you have enough of those already but it would never hurt to take it if it was a F303, I'm sure someone would take it off your hands!

It's funny - after seeing the Cressi rotors sitting for a week before doing the swap, seeing the 3rd gen/Mk II rotors sitting now, they look soooo small!

Was the braking balance (front and rears) disturbed because of the larger fronts. 

Awesome thread btw, very informative.  You got a great deal on the brakes,  I love junk yard upgrades.

My brake balance was so F'd up anyway - the drum brakes don't do diddly squat, so the fronts locked up way too easy, and then the leaking M/C didn't help, and the front is so far from stock...
I'll let you all know more after I get a chance to really go abuse it. Of course, then I'll throw the disc brake rear end and the Cressi proportioning valve in and be at square one again - time for an adjustable prop valve...

Great write-up. The pictures and directions right under it is really informative. I know this is one thread that many people will go back and read when they figure out how easy this upgrade can be done.

The other thing I liked about this swap when I did it, weight savings.  Maybe I imagined it, but the Cressida set-up seemed about 2-3lbs lighter per side.

i think you need the cressida hubs because if you try to put the cressida rotors on the celica hubs it'll mess with the offset of the rotor.

Yeah, I was looking at that and wondering, but didn't want to take the time to pull them apart to find out. It is just sooooo easy to pull the whole thing from the donor Cressi and put them on the Celi complete, I so no reason to even wonder.

Hmm, but if the 3rd gen hubs would work, it would mean those of us without a JY with 80s cars in it could buy the whole setup (rotors, calipers, and brackets) new from rockauto for about $150. Guess I gotta check the parts catalog tonight to find out if the hubs are actually the same.

even if you look at bob's picture you can see that the rotor's mounting surface is different. And the back spacing on the hub is different. I'm pretty sure you'd have caliper clearance issues.
