I also disconnected part of the wires, the car works fine, the alarm goes on for 10 sec every 5 min. But no screachng sound from the ABS. My mechanic will study the issue and will see if he can fix it. We all avoid the Lexus stealers. I bet that some of you who had old Jags are used to this

I'm still looking for the master cylinder.  Lexus will sell me a complete assembly for nearly £1990, although they will offer the two components separately - £1346 for the master cylinder and £1100 for the brake booster.  I guess from noise we need the brake booster part ?  

I have disconnected the plug like 'pb32' to stop the noise and warning signal and have lost abs and traction control but I managed without them in the Jag.

I'm not paying full price unless I have to so I'm looking around for a used part or maybe importing from the States if I can find someone.  

I have emailed Aisin but had no response (I think the email went to Belgium) so I going to ring their UK office tomorrow.

My car has done 130k btw

Hi Folks,

I'm new to the site.. I'm driving a GS300 98 model.. and have a problem with the abs.. the pump appears to be permenantly on..ultimately causing a squeaking/screeching sound and results in the ABS and Exclamation warning lights coming on together with a continuous tone alarm.. interestingly the brakes work ok and the only way I have been able to get the pump off is by disconnecting the three pin connector on the unit which I guess is the power to the pump..

i expected this to cause the brake pedal to go hard (lose power assistance) but the pedal is normal and hasn't gone hard.. any one had any probs with this that can help me ...thanks,  i called lexus and they cant look at it until friday..

I recently bought a 99 GS300, and have a similar problem, although the sound and alarms come and go. The car has about 70K. Perhaps the problem is more common than what we think. Did you find a master cylinder?

The car seems to work perfectly (even the breaks) but the noise is a pain,
