Will the ST185 front brakes fit on an ST162?

It just plug and play. Without ABS you just have alot less steel brake line.

 

its good you dont have abs, its the actual pump thats the pain, it reduces the brake presure and the lines as mentioned are far more complex and a pain to bleed.

bolt on goodness for you, to swap to the 185 mc you just need to bend one line, the 3 bolt holes for the cylinder onto the booster line up and its all good.

 

162 and 165 hubs (where the wheel studs are mounted) are the same, as long as you swap ABS with ABS and non-ABS with non-ABS.

The caliper is mounted on the steering knuckle, but I believe they are the same with 2 differences: ABS or non-ABS and a camber adjustment cam on the 86-87, which the 88-89 don't have.

 

Yes, the later cars have bigger master cylinder pistons

I think the 185 brakes are a waste of time, 202 are bigger pads and wider disks

Part of the confusion we're having is due to the fact that all the JDM models seem to
have the same disk diameters and only differences in pad size, piston size and disk thickness
wheras it looks like o/s cars got a multitude of different sized disks.

 

st185 brakes do work better. They have a larger rotor, and better pad/rotor choices. the st185 MC is slight bigger. I have a kit off my st165 with the brakes, lines, pads and rotors if your interested.

The st205 take a lot more work, though I have done bolt on solutions for both

 

Here is the specs for the ST162 (GT-S) vs the specs for ST185 (All-Trac) with regard to rotors, pads and such. ST162 rotors are 258mm x 22mm with a 48mm offset, and use pads with a 120mm width, 47mm hieght, and 15mm thickness, where as the ST185 rotors are 277mm x 25mm with a 46.2mm offset, and use 119.7mm width, 53.7mm hieght, and 15mm thich. The master cylinder has only about a 1/8" larger bore, but in dealing with braking force, that is a huge difference. Also while the rotor size isn't huge, any gain in surface area for heat dispursment will give greater brake force numbers.

My argument exactly, the 202 brakes are similar, cheaper and easier to find, master cylinders
can be scavenged from V6 Camry, Solara etc

Dunno where you guys think you're going to find all these 185 parts?

 

what are the specs for a beams 202 twin pot? are they the same as a 185

 

common stig you should know by now!!

Me

Ive got st185 twin pots, st185 sing pots, st205 4 pots, and if you keen to racing I even have willwood set ups.
I only have 2 cars, so I cant use em all

 

Don't know about the beams version, but US specs for the 202 brake discs read like this, 275mm x 28mm, with a 49.5mm off-set and pads measure out this way, 141mm wide, 62.4mm hieght and 17mm thich. Gotta check pad availiblity for racing if it's gonna work out for my needs!!

Did some more research, found that in my case the 185 discs and pads are the better choice. I have run Hawk Brakes and Brembo rotors as long as I've been racing, mainly cause the Hawk racing bucks are just too good, and the Brembos just last and last. In searching through the Hawk listings, the HPS model is the highest performing package for the 202s. The 185 set-up uses basicly the same pads as the 162, so I've got the choice of HPS, HPS-Plus, Blues, Blacks, and HT-10 pads.

Anybody got any pics? esp the 185 (like hens teeth here)

I fitted the 185m/c, it does make a difference - on your car you may be able to fit the bigger servo as well




162, 202, 165 pads


The 165 & 202 brakes compared = very little difference in dimensions
But when compared to stock 162 in this pic shows a huge difference in width/caliper only

 

Can't see whats under there, you'll have to take a wheel off sometime

162 (182 pads fitted)


202


165


Inside the 202's, Im punting them because they're cheap, available on Celis and V6's
and I suspect no different to the 185 brakes

 

i have a twin pot beams set up for free, will the master cyclinder fit? with the booster
