Dealing with a squeal from the front brakes
Gordon Hesketh-Jones (Harvest Gold V8 1904) from Cornwall provides
an interesting note on curing a persistent squeal from the front brakes
on a factory built MGBGTV8. (Dec 99)
Having put up with squealing front brakes on my MGBGTV8 for thirteen
years and 180,000 miles, I finally decided to sort the matter out
properly. Over those years I had experimented with all types of
brake pads and brake discs and, whilst some combinations provided
short-term relief, the dreaded squeal always returned. You will
of course know that brakes were originally fitted with stainless
steel anti-squeal shims but these have not been available for many
years. Our local scrap yard no longer have any early SD1 Rovers
which used the same caliper.
Recently I achieved reasonable success by making some shims out
of 0.003" stainless steel but the material was just too thin,
so the shims just twisted and broke up. I then found a local engineering
concern where I could get them produced and obtained a quotation
to have the shims made in 18swg stainless steel but found I would
have to buy a minimum of 25 sets to pay for the tooling. These shims
would bear a close resemblance to the original factory parts but
with small differences to avoid copyright problems. At this point
I contacted the V8 Register since before
After beginning the preparation of this note, I found a new product
made by Lucas and supplied by Moss as an anti-squeal kit for the
MGBV8 comprising self adhesive aluminium strips. They come as part
numbers 3GP02, GBP240ASK and PNO26581. I have
fitted a set and after 50 miles it seems to be working!

to V8 Workshop Notes Contents listing
Terry Harrison (Damask 1598) from Wiltshire posted a message
on the Bulletin Board seeking help with solving brake squeal on his
MGBGTV8. The topic was covered by V8 Workshop Note 215 in Volume 6
of the series which is reproduced below.
Footnote: We sought the views of Roger Parker (V8
Green 4092) on these anti-squeal kits and he commented that he noted
the use of self adhesive anti-squeal pads and can confirm they are
widely available from most auto shops under various brand names
on the packets. They have been introduced as a consequence of the
non asbestos brake pads now in general use which tend to be noisier
than the asbestos type. The adhesive pads, which are simply glued
onto the rear of the brake pad, act as sound dampers and absorb
vibration generated by the friction lining to disc contact that
is the source of noise.
spending my money I would have liked to have found out whether the
V8 Register has an existing source of shims from which I could buy
a set to avoid bulk manufacture, or alternatively, whether there
might be a demand for these parts from existing MGV8 owners if I
did order a production batch.
