If your Toyota Camry or Avalon's brake pedal feels hard or requires more effort to stop, the brake booster might be failing. This A-Premium replacement power brake booster is a direct-fit for 2007-2011 Toyota Camrys with the 2.5L engine (specific build details, check listing) and 2008-2012 Avalons. Important: This is the BOOSTER ONLY – it does NOT include the master cylinder. It has a 10.7-inch (271.78mm) single diaphragm and includes the push rod. It replaces a bunch of OEM numbers like 4461006301, 4461006302, etc. It's coated with anti-rust protection for longer life. They offer a one-year unlimited-mileage warranty. Installation requires some brake system knowledge – you'll need to transfer your master cylinder and properly bleed the brakes afterwards. A crucial part for restoring proper braking power and safety.
