Lexus ES300 Brake Booster
The Lexus ES300 Brake Booster increases the force of your pedal so that drivers brake with significantly less effort. Across the production run, Lexus fit the ES300 with two types of assists, the vacuum Brake Booster with which we are familiar and a hydraulic Brake Booster which is less common than the former, but with the same goal of converting light pressure on the brake pedal into a firm pressure at the master cylinder. The vacuum design contains a diaphragm and power piston within a two-piece shell, engine vacuum evacuates both chambers until braking starts, then admission of outside air behind the diaphragm via a pedal actuated valve, the difference in air pressure pushes the piston forward, multiplying the force exerted for stopping. A hydraulic Lexus ES300 Brake Booster taps pressurized steering fluid or an electric pump to provide assistance even during low engine vacuum. While the vacuum model is admired for its durability, the Brake Booster will provide only a few boosted stops if the engine stalls, and the hydraulic setup will continue to work as long as fluid pressure remains. All told, either booster allows the Lexus ES300 to provide confident braking under minimal strain on the driver.

Therefore, if this happens each time one depresses the brake pedal, with each cycle being shorter than before, then there is an evidence of seal on the booster. Still while running car engine press brake pedal and hold down even as you switch off ignition. The booster is airtight if no change in pedal reserve travel occurs after being held for 30 seconds. Remember that power brake boosters should not be dismantled during removal but have to be replaced with new or rebuilt ones depending on their condition and availability of these units together with special tools necessary for disassembling them. Consequently take out rear brakes master cylinder, charcoal canister and air cleaner assemblies after removing charcoal canister and air cleaner assemblies from throttle body upper cover as shown in procedure titled AIR CLEANER ASSEMBLY REPLACEMENT.

Lastly detach four nuts and washers securing power brake booster to firewall then pull it out. Once you have done this, do everything in reverse order tightening booster mounting nuts as well as clevis locknut firmly.
