Brake servo failure
With the introduction of the MGBGTV8 in 1973, the luxury of servo braking arrived providing reliable and powerful braking for the high performance MGB model. As the V8 model approaches its 50th year, a number of the components are clearly ageing and preventative maintenance needs to be considered. The V8 has a hydraulic braking system that comprises a remote or indirect servo on a single circuit braking system, so a serious servo brake fluid leak or a failure on the single brake circuit can lead to a complete loss of brakes. Consequently there is a real need to maintain the brake hoses, the brake master cylinder seals, the brake slave cylinder seals and the flexible brake hoses, not to mention the servo itself.

You can see illustrated diagrams describing how the Lockheed servo works on the MGBGTV8 and how they can fail on the “More” webpage

Over the years we have seen reports from members of over ten servo failures and three cases are reviewed in a feature article in the four page V8 Newsletter due to be published in the April 2022 issue of Safety Fast! which will hit members' doormats on or just before the start of April. It will be worth reviewing - if you go to the "More" webpage and click the link to "See all the V8 Columns and V8 Newsletters" you can see the forthcoming V8 Newsletter - see page 3.

Want to replace your brake servo?
Some years ago we ran a campaign to encourage members to replace their brake servo as a preventative measure and Brown & Gammons supported the campaign with a very good "remove & replace offer". Well on seeing the feature article coming in the V8 Newsletter Brown & Gammons have a special offer:

Supply a replacement brake servo for the MGBGTV8 model at at a discounted price of £195 plus VAT, that’s £234 (normal price £209 plus VAT) until the end of April 2022 or while stocks last. We can of course offer a fitting service too if that is needed.
