Gordon,

Excellent work. It's good to see the Lindsey body getting the proper attention. I love the Lindsey bodies trucks, but sadly you don't see them too often at shows...at least not on this side of the pond.

Hi Grodon

You may be surprised, by the original booster, both of my C60 have their original boosters and in both cases all that was required was cleaning and replacement of the bellows to get them working well. One of my trucks had been sitting out in a field for years when I got it and was in sorry condition. (As the photo below shows) I did find an NOS one years ago that is my spare if one of them starts to go south.

Because of the linkage design and design of the booster the health of the booster is readily apparent if you have your foot on the brake when starting the engine. The only part I have found to cause problems is the vacuum check valve which is in the line coming from the manifold and there are modern replacements for these.

I bench tested the booster unit, wish I could find my notes on how much boost it actually adds, the design of the booster and the linkage is such that your full foot peddle pressure goes through to the master cylinder with the booster adding to that. One of the particular things I was testing for in bench testing was bleed down time.





I agree about wanting to be sure of the brakes, my drive down the mountain road this weekend it wasn't the booster that concerned me but not wanting to discover brake fade would occur on 6 miles of 8+% grade on a winding narrow road. I just followed the old truck dictum go down hills in the same gear you needed to go up. There were several full stops coming down and the truck stopped without effort.

But please do keep us posted on your progress and what you do on the brakes. Bye the way do you need to reline the brake shoes?

To add to the list of possible booster units take a look at http://vehiclesofvictory.com/buying-...tion-to-parts/ main site http://vehiclesofvictory.com/ This is where we found two NOS CMP boosters years ago for $75 each, they didn't know what they fitted. (Yes they are both gone now) but you never know might be worth asking.

Cheers Phil

We have had some beautiful warm dry weather in the last week and I have had time to organize some sand blasting and painting. The upper cab and one door still need some metal work and finishing. Hopefully I can have all the major components painted and set aside to cure till fall work is completed. Then I can work away in the shop this winter finishing of the small bits and assembling the truck.

Here are a few pictures of the cab and chassis parts.

You give me great hope that my brake booster might be made serviceable, the exterior is in very good condition. A friend said maybe I s would get lucky and there would have been enough oil blow by from the engine to rust proof the interior. I'll ono better when I crack it open.

I agree with Phil, Gordon. If you are prepared to go through the entire original brake system and replace every rubber, brake shoes etc and have all the parts you should have... the brake systems on these trucks are very safe and work very well.

I completely refurbished everything in my truck (F60L Cab 12) and spent several days studying the manual in regards to set up/adjustments and learning how to get the booster working properly and I nearly sent myself through the windscreen... they can really work that well, fair dinkum.

The two critical things I found were correct brake shoe position when installing brake shoes with newly bonded brake pads and correct set up of the booster to achieve maximum vacuum assist.

I could blab on... but that'll do.

No mate please BLAB on i need as much info that you can throw at me. This is what ill be doing over the next few weeks. Oh and do you have photos on which order the parts you began to put on the truck as you did your restoration?

[Ganmain Tony]

I'll post a bit on your thread if you like.

I also forgot to say superb job to Gordon and enjoying your thread and pictures.

Can never have enough pictures...

Mate that would be great. Cheers Shane
