Technician Jonn has been working on the brakes of our 1956 Jensen 541.
Here are his notes:
Started by reassembling the rear brakes, Fit rear shoes and refit drums. Rears locked up once drums refitted. Unable to pump brake pedal to centralise as no shoes on front axle yet. Refit rear wheels and swap over to front axle. Refit front shoes and drums, all ok. Refit wheels. Pu,p brake pedal to settle. Go back to rear brakes. Found new brake linings fatter than old shoes. Going approx 1mm from the heel of each shoe and refit drum. OK now so repeat for other side. Carry out minor adjustment and refit wheels. Pump pedal and operate handbrake. Final adjustment to be made once car driven.
Take outside to check clutch and brakes. Carry out road test but broke down 1 mile up the road. Eventually managed to get it started and drive back on idle speed as it dies when revved. Investigate misfire/running issue. Found engine only running on 2 cylinders. Remove number 3 carburettor float bowl lid to find no petrol in carburettor. Pump priming handle on lift pump and fuel came out of feed pipe to carb. Refit float bowl lid and continue to prime pump. Put in 10ltrs fuel and start. Runw fine again. Leave to idle for 5 mins and then repeat road test. Same thing again, cut out and won’t rev. Get back to workshop on idle again. Check fuel filter. Has fuel I side but remove and replace with piece of pipe. Found fuel filter had not been manufactured correctly and I don’t know how the car even managed to run. Replace fuel,filter with a correctly manufactured one and repeat road test. All ok now. Clutch feels OK. Brakes OK. Return to workshop and adjust rear brakes.
