Hi,

New to the forum.

I have a 1989 Ford F700, with a Brazilian made 6.6 turbo diesel and I'm having trouble getting part numbers.

This was a rental truck when it was built and has a Lucas Girling brake system. I'm looking for the part numbers and a supplier for the upper and lower rear wheel cylinders. The upper cylinders, attach to the brake pots for the parking brake system. Most of these trucks were available with the L/G electric brake, or an air brake system. in my younger days, when these were common trucks, we would just replace the entire backer plate, which had both wheel cylinders pre installed.

I would really appreciate if anyone has either the wheel cylinder part numbers, or a number for the complete backer plate. As it is now, the rear brakes are completely blocked off. The Passenger side has no cylinders, or shoes in it at all and the brake pot is caged. the drivers side has shoes that are 95% gone, the lower cylinder leaks severely and all that is in use is the parking brake pot of the L/G system, which does nothing, as there is no fluid in the system to operate the cylinders. But I have not caged the brake pot.

The system was blocked off, so that we could get it home.

I have completely rebuilt the front brakes, thanks to finding an old Wagner Parts book under the seat that had a and written parts list in it, from 1993. (Hey, I'll take 26 year old information).

For my next amazing trick, The number 3 injector line had a serious leak, where it had rubbed on a bolt on the line loom. When I got it cranked the first time, it sprayed diesel up past the injector pump.

I took the line off and tried to find one, no luck... So, I took it to my shop, cleaned it up, polished the steel and turned my MIG as low as I could get it. After a series of quick pops, I had the hole filled enough to try to weld it. I was able to get it to hold the weld, but it is paper thin. it still has a slight drip. about 1 drip every minute. It was good enough to get it home, by its far from reliable, of safe.

So once again, I would really appreciate it if anyone has the part numbers for the injector lines. I specifically need number 3, but anyone who has the numbers for all 6, I would appreciate it, as I eventually plan on replacing them all.

Thank you in advance

10-15 years ago, Highway Truck Parts in New London, WI had a bunch of those 6.6s in his yard. They were in Ford school buses. Might be worth a call.

When I was at City of Cleveland shop 20 plus years ago, we were able to get exchange loaded backing plates for the Lucas Girling system . So I expect a heavy truck brake hardware vendor could get them. But a rear axle swap might be in your future to salvage the truck . Regarding the engine , Conway truck lines ran a bunch .

Hy Max, We would need to know the width of the rear brake shoes, the bore sizes of the wheel cylinders is dependent on the width of the brake shoes. Is this a mixed system with air controlled parking brakes but hydraulic service brakes?
