Re: rear speed sensors
Haven't ever seen how a 93 Ty is setup, but it should have a sensor on all four courners

Re: rear speed sensors
Oh good call, you might be right, never been in that exact spot on those. If it's 3 channel did they put it in the rear diff?

Re: rear speed sensors
Well Waller confirm's that there is only one sensor here, third post down.

Here also, 93-96 had a 3 sensor setup.

Re: rear speed sensors
Thank you for the info. I guess what I need to do now is try and get a 93 ty wiring diagram and see what is different from the 92 ty in the brake wiring. I would like to convert my 4 channel to 3 channel to retain abs and have bolt on inexpensive rea
r disks.

Re: rear speed sensors
Why do you want to convert it over? I don't see why you can't swap on discs without the sensors, most toss them anyway. One of those links even talks about how bad our ABS is and the big recall they had on it because it would cut brake pressure and you would have no pedal

Re: rear speed sensors
You might look into the LS1 caliper off a Camaro or a Vette instead, IIRC the S10 caliper in steel and LS1 calipers are aluminum. Just some food for thought.
Good info on getting the rear disc setup to work with the different ABS setups.

I couldn't find any threads to confirm the material they used in the rear caliper, but I know for sure the fronts were steel, so i''m 99% sure the rear s-series ones are steel also.

Re: rear speed sensors
Yes the fronts are steel. I've already put the larger 2 piston disks on the front along with the newer lower control arms and larger front swaybar. The reason I would like to use a blazer set up is that they are relatively cheap and I can use the ebrake without any custom brackets.

Re: rear speed sensors
I guess I'm confused. I need to eliminate the rear abs sensors and some how use the vehicle speed sensor (vss) to send a single to the abs. Can this be done by simply switching out the DRAC...or is it not possible without the electronicly controled transmissions?

Re: rear speed sensors
Yeah, I'm going to try and retain the rear abs sensors, but making them to fit with the rear disc parking brake setup is going to be challenging. I have the rear discs off a 98 up blazer or jimmy, and they bolted up with no problems. The only thing now is to make the rear sensors fit and getting the ends for the parking cables. The calipers are aluminum and the discs measure 11.5"

Re: rear speed sensors
They use pads on the inside of the disc for paking brakes(ie a drum type setup) I'm using my stock ty rear end with the stock axels so the tone rings are on the axels. It may be easier to change to the 93 set up from a blazer. I'm not sure how to do this though. I do know that the 93 typoohn set up is exactly like the 92 typhoon system.

Re: rear speed sensors
ok i will chime in on this..... i HAVE done this to a 92.
im assuming you got all of this hardware off of a 4wd 98+ jimmy blazer???
if so, then yes the backing plates, and calipers, and caliper abutment brackets will fit.
what doesn't fit is the 4x4 rotors,.....they look like they will fit, but when you try to put them on, they hit the backing plate before they sit flush on the axle flange. approx. 3/4 of an inch if memory serves me.
to remedy this use the rotor off of a 98+ 2WD blazer / jimmy.
they are approx 3/4 shallower than the 4x4 rotors. i bought mine at checker, and they were cheap, like 15 a piece new.
thier very close to lineing up then, but i think i needed 1 washer between the caliper brackets, and the backing plates.
ok now on to the rear sensors.... you can retain the 4 channel abs without mods to the abs.
ok, look under the truch, in front of the gas tank... there should be 2 seperate black 2 prong connectors with blue tops attached to the frame. these are the rear abs sensors. disconnect both, and all retaining clips that hold the lines.
next remove the bolts that hold the sensor to the backing plate,....remove sensor.
assembly......
after mounting the backing plates, mock up the sensor on the backing plate.... the same 2 bolts should be able to be used for mounting. now look at the wire that comes out of the sensor... this is where you need to drill a hole to let the sensor pigtail to pass through.
3 different options here....
1. drill larger oblong hole just big enough to allow entire pigtail end of connector to pass through the backing plate.......(this way no wire cutting.)
2. drill small hole through the backing plate and cut pigtail off, thread through, then re-connect.......(warning...good soder or wire connector a must!)
3. (my favorite) drill small hole through the backing plate, then get the gm terminal removal tool, it allows you to disassemble all gm connectors, without damaging them, and re-assemble them.
i hope this helps, i had mine on there for 4+ years, and 50k+ miles now no problems.

Re: rear speed sensors
I will now clear up some misconseptions about 98+ brakes both front and rear on a typhoon.
1) They will bolt up by using the 98 + steering knuckle and lower control arm that has a
better front stabilizer bar mount. The 98+ flex hose will not attach to the stock metal line the thread size is different as well as the flare size. The stock sy or ty rubber flex hose is too short to work with the 98+ calipers and metal brake line on the frame. so the solution would be to have custom metal lines made or get the mtal lines off a 98+ 4x4 blazer or s10.
2) rear disc off a blazer will bolt up to the rear housing. The parking brake cable will need to have the end cables replaced with 98+ 2dr blazer parking cables. The brake hoses will work with the stock metal lines.
The master cylinder from a 98+ blazer can also be bolted on , it is quite a bit larger than the stock unit.
