I just saw it and it was easier to ask than trace the lines out. My John Deere tractors and Cat diesels don`t use one.

Thats because your tracters don't have vacuum powered brakes or a need for vacuum powered ac and heater doors under the dash.... Or vacuum to run the cruise control.... If you convert over to hydroboost brakes you wont need the vacuum for them and... You will double your braking pressure in the hydraulic lines to each wheel... That right there is a big plus for most....

I have a 24 ft enclosed car trailer that I haul the Vettes and Austin Healeys in and hydroboost would help the brake controller stop the whole mess. But stock or hydroboost once the wheels are locked up why does it matter. Other than less pedal pressure what benefit is it. And if it ever got that bad I would be so scared the brake pedal would be through the firewall by then.

If you have abs your wheels shouldn't be locking up anyways.

My '88 had ABS on the rear. Not the front. Don't know if it was standard in 88. Just got this '87 and haven't really checked it.
