Wing Removal and Servo Mounting

Preamble

When undertaking any work on the braking system, ensure you know what you’re doing. If there is any doubt in your mind, consult a specialist.

The standard brake system on LGL is more than sufficient to stop the vehicle but in certain situations one might wish for a bit more oomph! One of the easiest way to improve braking without too much expense and faffing is to install an inline brake servo. So named as it sits inline of the brake pipe runs and is not fixed directly to the pedal box.

Girling or Clayton inline bake servos were fitted to 6 cylinder 109” export models (and possibly as an extra for UK domestic vehicles) but not to the 4 cylinder models. That said, the Girling catalogue shows an inline servo for the 88”.

Girling and Clayton servos are now as rare as hens teeth and would need a professional strip down and rebuild before they could be fitted. Fortunately, Lockheed make a faithfully copy of the original and that’s what is being fitted…. Welcome the Lockheed Powerstop. These servos are fitted universally to a lot of British classic cars. They are even installed on the clutch system to make the pedal lighter.

It’s important to install a servo with the correct amount of vacuum. Too little and you’ll not appreciate it. Too much will make your brakes behave like and on / off switch. For the 88″ Land Rover, Lockheed recommend the 1.9:1 ratio unit.

Procedure

  1. Disconnect battery
  2. Remove air filter assembly
  3. Remove bonnet support and spare wheel and swing bonnet out of the way
  4. Disconnect lamp wiring in passenger side wing
  5. Remove passenger side wing and mud shield
  6. Fix servo to top of drivers side wing
With the wing removed, there’s a lot more room to work. This is particularly useful for accessing the 5 way brake line manifold and the clutch slave cylinder.
Brackets are well made with a deep powder coat finish
Brackets fitted, time to find it a home on the passenger side footwell…

The instructions call for the servo to be mounted on a surface at an angle of between 25 – 45 degrees from horizontal. The top of the Land Rover footwell is at an angle of 30 degrees! Superb.

Servo installed and fixed into position. It’s important to check the wing can still be fitted with the servo in place and that all the pipe and hose fittings can be reached.

Next the brake and clutch lines are removed, the two systems drained of fluid and new pipes made and installed.
