Running Repairs – Fuel Pump and Rear Brake Overhaul

While travelling to and taking part in a parade lap at The Silverstone Classic this summer I had a couple of odd incidents.

  • While passing travelling across country, the car cut out and coasted to a stop – restarting after maybe 20 seconds.
  • While on the parade lap at Silverstone the fuel pump (just behind my seat) went crazy – knocking and clattering away.

Knowing that I already had a spare fuel pump ‘in stock’ I decided that would be a good 1st step towards fixing the issue.

The job was a simple one, but included removal and refitting of the drivers seat to gain good access to the retaining bolts.

Since replacing the pump, the car has had zero problems – and I’m considering it fixed. In fact, the car feels like runs even better, especially at mid-high revs, maybe the old pump had been on its way out for a while.
I also took some time to pay attention to the rear brakes, the handbrake was more-or-less ineffective and, when attempting to bleed the rear brakes at the time of wishbone replacement, I could not undo the bleed nipple.
This turned out pretty time consuming, but easy. I replaced both rear wheel cylinders for the drum brakes and took some care to adjust the (supposedly automatically adjusting) handbrake.
I then re-bled the entire braking system.
The result of this is.
  • The handbrake works without pulling it up to the sky.
  • The car is much more stable under braking.

Upon removal, the old wheel cylinders felt as if notches were worn into the bore, and, my guess is – doing nothing in particular.
