I just bought a 99 GS300 with a hard brake pedal and beeeeeeeeeeeeeeeping noise. Brake light is on but the other 2 VTC and I never see they on (maybe previous owner disabled).
I been research forever for a fix solution with out spending $2200 for a new one or gamble with another old one like $400-$500.

so I pull the 2 wires that go to the beep speaker right on top of the brake pedal. That **** give me headache . DISABLED that.

I took ABS unit out the car 4 screws from inside and pull the pin. I pulled all the plug and the unit wiggle wiggle it out.
lose 2 wires from the module to the motor and applied 12V direct from the battery, NOTHING happened. No turning, no noise. So... I lose 2 allen screws that motor mounted on and the other 2 allen screws from the adapter plate (between the motor and the .... fixture). Bend the plate behind the motor and then took the motor apart.
First thing I noticed is the 2 pieces of the collectors are missing ... or ... dusted...

I hope this is the common issue that everyone and I frustrated about.
Now I need help to find the collector piece, where to buy/order. I took few measurements so yall can help me or yourself.
Check out the pics.




2 of the collectors are gone.





~0.84in diameter of the collectors





~0.875 upper bearing





~0.59 in bottom bearing

 

more researches came up with Mitsubishi Pajero 2000-2003 with ABS, they are looks alike. May be Toyota and Mitsubishi favor Aisin products back then.

 

I know is a company that only sell it those bearings, but I can remember the name of that company. Try to google it with the measures that are you took. You can also try MSC Industrial Supply.

 

I went to that website and couldnt find what I need. The piece I need is called "commutator".
The spec of that piece is 12p (12 tabs)
23mm outer diameter
9mm inner diameter
12mm is the length or height.

 

When I stopped by Lexus the other day I was able to look at the whole ABS diagram. They sell it in pieces too. not just the whole piece. I saw part numbers and everything.

 

are you sure ??? which Lexus ?? I want to call them and order it

 

hey any luck finding the correct commutator
