to articles on servo failures with an MGBGTV8 Fortunately
brake failures from servo problems are rare but, unlike difficulties with slave
cylinders where early warning signs can usually be detected, early warning signs
of potential servo failure are few. But servo failures have been reported by V8
members but fortunately at low speeds and without damage to the car or personal
injury. If you have had the experience, thoughts of the consequences of a sudden
servo failure at speed are spine chilling!
Here are links to a number of useful notes which hopefully will encourage
fellow members to get their servos checked and better still replaced.

brake servo failure reported Barrie
Jones reports "there are three V8s that regularly attend my local natter
in Cornwall. and one
of them has just had a brake servo failure. The master cylinder was sucked dry
without warning". 140503

Another
servo failure reported Longstanding V8 enthusiasts, Mike Dunlop
with Limeflower 0118, has reported a servo failure. Fortunately like Jim Gibson
it was detected on start up - the garage was filled with white smoke as the brake
fluid burnt off as it leaked into the inlet manifold from the servo. 120212

V8 servo check-up campaign
 | V8
brake servo check up special offer | For
six months in 2009 the V8 Register ran a campaign with the support of five specialist
garages encouraging fellow members to have their servos checked and replaced as
a precaution. Although the special offer the specialists supported during that
campaign has ended, the note highlights who they are so members can contact them
for this vital service item. More
Brake systems and servos on the MGBGTV8
and RV8 Peter Garton with an RV8 from Germany started a thread
on the V8BB in August 2007 by posting a message wondering what would happen if
the brake servo on his RV8 were to fail. This note brings together the responses
to that thread, particularly from Bob Owen. Clearly the braking system on the
RV8 is a considerable improvement on the earlier system used in the MGBGTV8 some
twenty years earlier and provides better protection against the consequences of
brake component or system failures. More
TE low
brake fluid sensor - a vital safety device for an MGBGTV8 Bob
Owen suffered one of the brake servo failures we have reported over the last few
years and decided he would like a little more warning if the brake fluid loss
might occur again! He was well placed to create an electronic sensor which fits
on the brake fluid master cylinder cap as he runs a successful small electronics
business. This kit was launched at the Club's annual International MG Meeting
at Silverstone in July 2005 where V8 enthusiasts were be able to see a demonstration
unit and many decided to buy one. The kit is described in

brake servo failure caution There
have been five or six servo failures reported over the last ten years where the
unit swallows the brake fluid relatively rapidly and leaves the driver with no
brakes. For those who have had that spine chilling experience they would urge
you to have a 40 year old servo examined off the car and where necessary professionally
refurbished. An alternative is to invest in a new servo because the reliability
of your V8 brakes is not something to scrimp on that cost is modest in
terms of your peace of mind and safety More |
