Hello,
I have a 1994 F600 GVWR 21000. Never really worked on big trucks so I don't know what options are out there. It is low mileage truck and I was wondering what my options are in replacing the entire rear axle assy to get rid of the Lucas-Girling system that I currently have. Right now the system works perfectly w/o and problems or leaks. What I would like to do is have a different rear to install when this one starts to give me problems, given the cost of repairs. Is it possible to swap out the rear axle with a system that isn't a Lucas-Girling system? The truck runs great and does everything I need it for, so I hate to get rid of it, but if I have no options with replacing rear axle I may decide to sale it while the braking system is still working.

Thanks in advance for your feedback.

 

You want air brakes or just another type of hydraulics?

Pretty expensive course of action given your system works.....???

 

My buddy had to have his system rebuilt and it cost him $1800. I would like to have a plan (another axle) ready if and when mine quits. I own a garage, but never worked on big trucks so was wondering what my options would be. Can I get a rear (juice not air) from a year that didn't use Lucas-Girling system and swap out the entrie rear axle? Don't see why not but I thought someone on the forum may have first hand experience.

 

Front axle too? A lot more than $1800 if you figure labor.

 

I recently purchased a 83' F 700, 370 4V, 5 speed, 23100 GVW, No Lucas-Girling brakes on this truck,(one reason I Bought it)Has the Manual Emergency Parking Brake handle (next to your left knee on lower Dash) Brake works Great, Has a Rockwell Rear with single line Hydraulic Brakes on it, so I would think your solution to that Braking system is do-able, but you will need another Parking Brake option!
The Parking braking setup on my F700 is on the back of the Clark 5 speed tranny.

 

The Lucas-Girling brake system was a high maintenance item in our municipal trucks in Cleveland . Our brake vendor came up with loaded backing plates that was ready to bolt on your axle , connect up the brake lines. But sometimes you'd work on them every week.
