Description & Operation
WARNING:
For warnings and procedures regarding vehicles equipped with Anti-Lock Brake Systems (ABS), see appropriate ANTI-LOCK article.
NOTE:
For disc brake coverage on Lexus LX470, see Land Cruiser information in this article. The 1999 Land Cruiser and Lexus LX470 information is the same. The 2000 Land Cruiser information for models equipped with traction control ABS is the same on 2000 LX470. Models with traction control ABS do not use a Load-Sensing Proportioning Valve (lspv) and By-Pass Valve (BPV).
Hydraulic brake system uses a tandem master cylinder with a vacuum power assist servo. All models (except Land Cruiser) are equipped with front disc brakes and rear drum brakes standard. Rear disc brakes are standard on Land Cruiser models.
A Load-Sensing Proportioning Valve (LSVP) is used to regulate brake pressure between front and rear brakes. Rear brakes on all models are self-adjusting.
Parking brake lever mechanically activates rear brakes. On models with rear drum brakes, a cable applies rear shoes. On models with rear disc brakes, parking brake is a drum brake internal to rear disc assembly.
