Avalon Brake Booster 1995-2003 OEM 53-2766

This CarQuest brake booster for 1995-2003 Toyota Avalon restores factory pedal effort and vacuum-assist boost with fresh internals.

The vacuum brake booster is the round canister behind the master cylinder that multiplies pedal effort so the driver does not need to muscle the brakes down. Boosters fail two common ways: the internal diaphragm leaks vacuum, giving a hard pedal that softens once the engine starts, or the check valve stops holding, showing up as a hissing behind the pedal at brake apply. A remanufactured booster comes with a fresh diaphragm and vacuum-tested internals and restores factory brake feel.

Verify your fitment with the year, make, model, and trim of your vehicle before ordering. If you are not sure, contact us with your VIN or vehicle configuration and we will match the correct part to your application before you buy.

Cross-Reference

Manufacturer part number 53-2766. This is a CarQuest catalog part. Confirm the OE reference for your vehicle matches before installing.

Why You Might Need This

Signs of a bad booster include a hard pedal that softens after the engine starts (or vice versa), engine stumble at brake apply (the diaphragm is dumping vacuum into the intake), or a hiss from behind the pedal under load. A rebuilt booster restores factory brake feel and pedal effort.

Installation Notes

Confirm the vacuum source is intact before installing a new booster. A booster failure is often traced back to a cracked vacuum hose, a leaking check valve, or a failing intake manifold gasket. Replace the vacuum hose and check valve at the same time as the booster if either shows any cracking or wear.
