Hi all,

I just got my ST205 half cut and it came with ABS. The question is, is it better to go ahead and install it on my ST202? any reliability problems, brakes jamming...etc

thx

i dunno but you dont have the rear abs things so i would say its useless???

do you really need abs?

if you dont have abs in the car then it would be a massive job to install it ( you cant just have abs in the front)

ill take the front sensors off you if you dont want them.

>

The H/C came with the rear rotors and calipers + ABS Sensors, i just have to modify the solid metal hose going to the rear...

do i need it? i would say yes, it rains alot down here

My concern was its reliability...

>

installation is no issue, reliability and effectiveness are...thats why i need feedback from the dudes whom are using it

Abs on a celica is very reliable i have it on my ST.
Be careful if you want to take the sensors out of the hub, i wrecked mine when i replaced the wheel bearing and they are very expensive parts.

in that case ide say yeah if you can be bothered going through the massive task of installing the stepper motor and running all the hard lines, and wiring in the abs ecu.

its very effective and relaible, and if anyone tells you they can stop better without abs then with they are full of ****.

I duno if the 202's have the same abs units as the 205s (when they are factory abs i mean) The 205 abs has g sensors in the stepper motor that can diffrentiate between cornering and straight line breaking and hence give the correct ammount of braking force to the correct wheels at the correct time. Toyota called it "sports abs" and was pretty advanced for 1994.

Great Info dude...THX!

revival from the grave. but concerning the different in gt4 and celica that came with superstut and abs.

American ABS brake system for ST204 have completely different part #. whats the benefit of the sport ABS found on Japanese celicas

Isnt this called TRC? I know Japan spec Celicas have TRC and TRC OFF light in gauge cluster. I dont think ABS is able to help cornering.

Also, there was a update on the ABS unit when the facelift models were launched...can anyone confirm this ?

I've read about the ABS control system from the GT-Four using additional input from accelerometers, and not only wheel speed sensor input.

I'm guessing with the accelerometers, the control system takes corner weight due to weight transfer into account so the pumping frequency of the abs can vary based on how loaded each tire is for better performance. just a guess.
