Does anyone know where i may be able to track down a new diaphragm for a retro-fitted lockheed brake servo?
the only thing i can find at present is the servicing kit at £80-00 and i can't help thinking that there must be a cheeper option!
cheers

There are complete servo kits on Ebay for £79. Failing that, there is a company called something like Norton or Newton who recon servo units.

Are these genuine Lockheed /Delphi, if not avoid them like the plague.

Fitted an £80 Remote Servo as a replacement to an Austin 1300 GT last year.
It looked the part and was exactly the same as the old unit.
The brakes worked fine, the problem was that the brakes kept on hanging on (dragging).
This had never happened before fitting the new unit.
After replacing most of the rest of the braking system including master cylinder it still happened, so I removed the servo altogether and returned the car to it's original factory spec of no servo.
Now the brakes work fine with no dragging.
My advice would be to renovate the servo you already have, if you know it once worked . Usually the diaphragm is ok, it's the hydraulic seals that need replacing

I think there must be something wrong with the servo if it needs a new diaphram. We have had cars in regular use over 16 years and none have required work. I'd searcgh around for a new unit, no point in spending £80 then finding it still fails.
Cheap servo's are exactly that, and with these and other brake items buy by name not price.

Leo did you modify the master cylinder? as it is a major cause of discs holding on

Jonathon some parts suppliers are supplying Caparo brakes as 'Original Lockheed' is this correct. PM me if you cant reply

No it happened with the original master cylinder and again with a NOS replacement
I also replaced all the flexible hoses, reconditioned the swinging calipers with new pistons and still the problem persisted.
Removing the servo worked with immediate effect, and apart from more pressure required on the brake pedal the car now drives fine with no hanging on

The 1300 GT was designed for discs - it doesn't have the 'top-hat' seal etc.
For this Minor I suggest you remove the servo - and just run the car without! Is there any special reason why it has a servo ?
