Someone had asked for the TSB numbers and info previously, so here goes

L-SB-0011-11

Applies to:

2007-11 GS350 & GS450h
2006-07 GS430
2008-11 GS460

This TSB is for 2WD models only... Some IS & GS models may exhibit a squeak type noise from front brakes under light braking. Updated pads, rotors, and shims have been developed to remedy the problem...

(Sorry that part numbers are not provided at this time)

and then the other bulletin

L-SB-0040-09

2007-2008 GS350 AWD

During light brake application, some AWD 2007-08 GS350 may exhibit a squeaking type noise from front brakes... Updated rotors, pads, and shims are available

NOTE: This TSB includes that the noise is made during "cold" weather conditions, and the first one does not...

Hope this helps for people needing the info

 

This is really good info. I changed my brakes and the there's a very loud squeak in the front pads. MInes not an AWD but maybe the update will fix it anyways.

 

please note that the tsb is under 50k miles or 4 years

 

Big brakes squeak too
