What is this part and why does it matter?

The brake vacuum booster multiplies the force the driver applies to the brake pedal, using engine (or pump-generated) vacuum, making braking effort much lighter.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Noticeably heavier brake pedal effort
  • Hissing noise when pressing the brake pedal
  • Pedal feels firm immediately, even with the engine running (loss of assist)

Installation information

Requires disconnecting the master cylinder and pedal linkage — always check the pushrod adjustment is correct before finishing installation.

Frequently asked questions

A failed booster (from a vacuum leak, internal diaphragm failure, or check valve fault) removes the power assist, meaning the driver has to provide all the braking force manually — a very noticeable, sudden change.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
