The first indication of a problem was that the car would not accellerate easily, I decided to pull over and in doing so noticed that the brake pedal had become incredibly hard with minimal/no travel.
On stopping I noticed that there was smoke coming from the front calipers. After five minutes standing, and several pumps of the brake pedal, pedal feel returned to normal, the wheels turned freely and the brakes functioned as before. I was able to make it home at a steady slow pace.
My instinct is to suspect the servo, a single replacelement Lockheed item activating both brake circuits. However, I am something of a newcomer to the world of car maintenance. Any suggestions and recommended remedies would be welcome.
The car was last serviced six months ago.

my plus 2 (1967) did the same...it was with the original girling servo.....
I put up with the intermittant clamping on as I couldnt find the problem until the seals of the servo collapsed as I came upon a roundabout at the end of a bypass....
trying to stop from 80mph with no brakes is somewhat frightening.......I would therefore suggest that you either rebuild the servo........or buy one that has been reconditioned ......or replace it with a lockheed servo unit.....I personally went for the lockheed replacement as they can still be sourced as can the bits....where as the girling unit is obsolete and the new set of seals/O ring are very hard to source.........
the smell of fear is not good so I suggest acting sooner rather than late unless you plan on keeping the top speed to about 5mph
the recon girling unit is also more expensive than the lockheed servo.....I payed ?200 fitted for mine in August (lockheed fitted) where as the recon girling unit was ?193 +vat.......
there are a couple of good places if you need contact info give me a shout

Following advise from lockheed help desk who told me that this was common reported fault with lockheed servo on plus 2, I remounted servo in different orientation as per their advice. Previously the servo had been mounted with air valve (white cap) at top - ie 12 o clock position. They advised that it should be mounted at either 4 or 8 o clock position. Also ensure that the outlet of servo is slightly higher than inlet to aid bleeding. Did this and no problems since (five years later).
Hope above helps
