Bonaldi Duplex brake servos


The dual-circuit Bonaldi duplex brake servo / booster is a complicated unit and many people struggle with these.     We offer a full strip down and rebuild service and also have testing equipment to thoroughly test the units before fitting them to the car.   The rebuilds are done in-house and its something we’ve done for 20+ years.

We receive these from all over the world.

We can also test in conjunction with your master cylinder and reservoir so we know that everything is working together, as it should be.

We can also supply seals, replacement pushrods and vacuum chamber gaskets on a mail order basis.

If you have an earlier car with the Simplex servo, then we can help with that too.
