Moss Recall

[Patrick67BJ8]

Guys.

There seems to be some misunderstandings about the recall. I hope the following clarifies things.

Here is a copy of the recall text and a link to a copy of the complete recall package. The recall only covers Classic Gold brand Girling Centre Valve style master cylinders. This is the type of cylinder used on the Austin-Healey that has a foot valve at one end to close the port to the reservoir.

Begin copy:

The Moss Technical Services department has determined that between approximately March 1, 2010 and February 1, 2011, we received, and sold brake master cylinders from a single manufacturer under the brand name Classic Gold with an internal design element that may fail in use. Specifically at issue is the foot valve. Although no one had reported a foot valve failure in an installed master cylinder, it had been suggested that because the foot valve design differed from an original Girling design, it was suspect. There are many different foot valve designs, so the difference in appearance or design is not, in and of itself, a cause for concern. However, the manufacturer of the master cylinder did not have test data on this particular valve. We suspended sales and arranged for the brake master cylinders to be tested according to SAE standards by an independent automotive testing laboratory to determine if there was a risk of foot valve failure in use.

Foot valve failures were experienced during the extreme pressure test at 3,000 psi after 10,000 cycles at 248º F during a heat durability test. The pressures and temperatures used in the test far exceed the pressure and temperatures you would experience with the master cylinder installed in a car, but the failure of a foot valve is serious because it closes off the port to the brake fluid reservoir when you step on the brake pedal. If it fails, the brakes could fail.

Moss is therefore voluntarily recalling the brake master cylinders that share this particular foot valve design.

A Notification will be sent during the week of August 1 to all direct purchasers of these master cylinders describing the recall and the products affected.

Please note, if you have directly purchased a cylinder included in this recall, you will receive a notification by mail. Use the documents in the notification to return the cylinder/s.

edit: The pdf package above was created for people who purchased cylinders covered by the recall from wholesalers, or who purchased a vehicle with the cylinder already installed.

Lelvin,
My brake & clutch master cylinders were part of the recall and have been sent back to BCS(where I bought them). I appreciate MOSS' responsible response and compensation was very fair.
Thank you,
Patrick
