    Brake servo recon info

    My brake servo ex (Ital)fitted to Marina based SWB Marlin has never been serviced, it came of a scrap heap some years ago. I wonder if in fact it has ever worked as it should - any advice please as to the best way to test unit. If indeed it needs replacement are there service exchange units available? thanks.

      I worked some years back for AP Lockheed and to the best of my knowledge no service exchange units were ever available for either Lockheed or Girling. Due to the need for specialised tools neither were service kits made available other than the filter assy .They rarely seem to go wrong in my experience.

          Have you looked on ebay? They sometimes come up as New Old Stock, and only make around £20

              to test operation of the servo - sit in car,apply footbrake and then start engine, the pedal should move under your foot. With engine turned off apply footbrake around 3/4 times, it should feel a lot more 'solid' when all the vacuum is exhausted.If no difference is felt then it's probably not working.You could also disconnect the servo hose, plug the aperture with suitable dowel/bolt and test drive with caution!! again you should notice a difference in effort required.

                      The works manual for Triumphs that used a remote servo (Girling Powerstop) suggests changing the seals every 36,000 miles or 3 years which ever is sooner.
                      Preferably by sending the unit back to Girling.Although there was a service kit available then.Also the units air filter should be changed every time the pads are replaced.
                      Another point to watch for is a smoky exhaust and consumption of break fluid without any obvious leaks.
                      Practical Classics had a couple of units referbished by a company called SNG Barratt but no other details sorry!

                          In addition to Alan's comments, if when you push down on the brake pedal, with the engine running, the pedal should move closer to the fire wall BUT if it then gives a little kick back this indicates a worn internal servo seal.
