I just looked at some threads about Hannigan parking brake kits.I have a 99 GL1500 and just put a down payment on a 05 GL1800 with Lehman conversion that I will pick up on july 1st. Both don't have hand brakes.Has anybody here looked into hydraulic inline brake valves( Wilwood makes several different ones)? We used those on our Detomaso Pantera race cars.Installation should be pretty straight forward
