98 ES300 rear discs on a 97 5sfe camry?

[97toyotacam]

i have done research and it says you can do a brake swap on the rear of a 97 i4 camry to the es 300 rear disc brakes. is 98 too new of a year to do the swap onto a 97 camry? cuz i found a donor lexus but i wanted to know if all the parts are compatible including the parking brake system. THAnks i tried to research as best i could but felt i still needed to ask just to be sure.

[RichieRichJP]

ASG14 could answer this one...
I have some brembos that I REALLY REALLY need to get rid of.
Let me know..

[ASG14]

Yes, they will work fine. You need the backing plates with all parking brake hardware attached, Calipers, Caliper Bracket, Pads, Rotors, and parking brake cables (The 2 from the brakes back to the middle of the car under the heat shield).

[97toyotacam]

Thank you guys i really appreciate it. Brembos sound good but right now im just focused on getting all the parts ready for the install. Hopefully i should be able to pull everything off of the donor es300 i need but i haven't actually seen it yet so i don't know how its gonna turn out. This is my next project. thanks again peace

This is one of the most worth while mods that can be done to a 4-banger Camry!!! I'm very happy with mine.

[RichieRichJP]

Ok, but you know you buy cheap rotors and they'll build rust...

Don't you have to grab the proportioning valve and master cylinder too? M/C = NO!

The 95 and 96 have proportioning valve on the cowl. I never checked the pn to see if its same as for drums but I can't imagine it is as the operating pressures for drums are way lower than disc. Although the car may stop, your rear bias could be so low that the new rear disc are not applied as much and end up being less effective than a properly biased (and good working order) drum set.

The point being, w/out fixing the proporting valve, pressure applied to the UPGRADED CALIPER PISTON is likely lower than what it could be due PV valve (bore difference of 21mm drum vs 38mm disc).




Hardware Specs:

Camry 95: (w/ or w/out abs)
Master Cyl dia: 25.4mm / 1.00"

Front Caliper diameter: 57.15mm / 2.25" V6 or I4
Rear Cal: 38mm / 1.5"
Rear Cal Wag: 35mm / 1.37"

4cyl Rear piston dia: 20.63mm / 0.8125"

Rotor Size:
Front: 10.8" vented
Rear: 10.6"
Wagon Rear: 11.33"

I saw conflicts with the Wagon 4WD rear piston 35mm vs sedan 38. Some list both as 38mm. They could use different pads and caliper hangers to make up the wagons weight difference and maybe use the same piston on the Sedan. IDK!





For Comparison!
============================================
98 Lexus ES300 V6
MC: 25.4mm / 1.00"
Front Caliper: 60.0mm / 2.375"
Rear Caliper: 38mm / 1.5"

ROTOR:
Front: 10.825" vented
Rear: 10.6"

98 Lexus GS 300:
Front Caliper bore X2 @ 43 or 45mm (Conflict with Dual Piston #'s)
Rear Caliper: 38mm / 1.5"

Front Rotor: 11.65"
Rear Rotor: 12.08" <not reversed, rear is bigger>

Don't have time to go any further but I'd like to see what all can be used myself! So if anyone has some info to add after this, I'll copy your data in here.


FYI: this bendix site (once drilled into) gives all the manufactures PN. Good if you want to cross reference PN . . .

EDIT: After doing research, all the masters are 1", but it still lists many PN

EDIT: 2010-06-25, adding the following. . .

Ok, thats too much for me to read.

Gen 92-01 Camry/ES and 99-03 Solara brake setups are all interchangeable, front and rear.

The Best front brakes:
94-96 ES300
94-96 Camry V6 w/ABS
95-96 Avalon (maybe ABS only?)
They were all twin piston.

The 92-93 ES/Camry and 94-96 Camry w/o ABS used the same pad, but a single piston.

The Gen 4 Camry and Gen 1 Solara used a much smaller caliper and pad.


For the rear:
92-96 ES300
92-96 Camry Wagon V6

Those had a rear rotor that is 3/4" bigger diameter, while using the same caliper. It;s a stock Big Brake Kit.

The In '00 for the Camry/Solara, the rear caliper and pad size got smaller.

Any rear 92-01 disc setup can be swapped on a 92-01 with drums. The only difference between them is the Parking Brake Cables. You need to use 92-96 cables on a 92-96, and 97-01 cables on a '97-01. So if you get a rear disc setup from a 99, and are putting them on a 95, you need to get 95 cables.

I;ve done several rear drum to disc swaps on Camry's, and yes, while the proportioning valve is a different part number, it still seems to work just fine.

I;ve sold a few rear drum to disc kits, as well as written a DIY for the swap. It;s fairly straight foward, just takes time.

[uibalnme]

I can testify to the effectiveness of this swap. It is a vast improvement over a "properly biased" drum setup. I have already done several 60 to 0 stops, and every time the stopping distance was far shorter than it was with drums. Not only are the stops shorter, but I don't have to apply as much pedal pressure as with the old drums.

I didn't swap the MC or PV. Swapping the PV alone would require removing the intake manifold, and whatever else is back there to get enough space to maneuver simple hand tools, and get the old PV out. Heaven help you if round off one of the fittings.

I tried to get a PV out off a Camry that already had the drive train pulled. Even with all the room in the engine compartment to work in, I still rounded off a few fittings.

Anyway, ASG14 is the master of the drum to disc swap. Never question the master!!!

[73sport]

I'm just sayin, theres a large audiance here and people need to know all the details. I didn't say it won't work or its not an improvement.

I've done plenty of drum 2 disc before on other cars/trucks and they work better when the MC delivers full pressure to the rears. . .
>Because our focus is sedans, most are sprung to soft and dampend so little they can't utilize the maxiumum effectiveness of such a conversion anyway so its moot point.

[uibalnme]

Science Alert!!!

The following link shows perfectly the physics behind what happens in a drum to disc swap w/o MC or PV from donor car. I think the 3rd animation on the page is a perfect example of what happens when the small pistons of a wheel cylinder are replaced with a large piston of a caliper in rear disc swap. Just click on the red arrows in the animations to see what happens.

http://auto.howstuffworks.com/auto-p...pes/brake1.htm

Bottom line:
The reason why swapping the MC/PV isn't needed is hydraulic multiplication.

[97toyotacam]

A ton of info here i read most of it. I think since these guys have actually done it they know what they are talking about. I am going to see the donor car on monday and i hope its in relatively good condition. I did hear from a friend of mine that drum brakes are a little more maintenance free due to the fact it is a sealed mechanism and is more resistant to moisture and rust in hawaii. I don't really care though i want those rear discs

They're not sealed. They are just like regular drums, open to the elements. The only difference being that they don't engage when you step on the pedal, the calipers do. The only time the rear shoes are used is when you pull the parking brake lever after you've parked or in a emergency stop situation where the car has lost all hydraulic pressure in the braking system. It's that reason the rear shoes don't wear out that quickly, if ever, and require very little to no maintenance at all.

FWIW:

There are at least 3 different proportioning valves on our base camry models according to BR.PDF for 95/96 years.

Disc/Drum
4 wheel disc
4 wheel disc w/ABS

Under light stopping loads, the Proportioning Valves (PV) delivers 100% of the master cylinder pressure to both the front and rear brakes regardless of the system type. However as the pressure applied goes up (harder braking), the PV drops pressure to the rear brakes on all models to reduce wheel lock-up.

From drum to disc the differnece is roughly 6% and goes up.
From drum to ABS (4wdisc), the difference is 10% and goes up. Here the ABS system can control the wheel(s) to prevent lock-up, thus they can apply more pressure to the rear brakes.

So, for normal moderate braking the swap works fine as you reported as the MC delivers equally front and rear. But for heavy braking you could gain more stopping power by swapping the PV valve in there too.

Depending on the coil spring rates of your car (nose dive, weight transfer, ect), this could help you (if you have higher spring rates in front than stock) or it could hurt you if the front springs have lower rates.

EDIT: 2010-06-25, I confirmed that disc and drum cars have the same resovoir size and PN

My front and rear is nice and stiff with the tokico blue struts and i bought new oem springs when i replaced those so i would say i have a good deal of stiffness compared to some camrys. I checked out the es300 yesterday and it was too rusted for my liking so i passed up on that opportunity. I did find a recently totaled (in the front end) 94 camry wagon but i have yet see its condition, though i am very hopeful on this one. how hard is it to get parking brake cables for a 97-01 v6 camry? i know i would still need this part after i pull everything off of the wagon.
