Alpine Parking Brake

I attempted to park my 1998 36 Alpine on my steep driveway and discovered that the park brake will not hold the coach on that steep of an incline.

Is this a matter of adjustment?

Is the 1998 parking brake the same as later models?
I found a picture on the forum of a 2004 34' Alpine parking brake and linkage. Posted by shorty50 on 5-16-2015.

Is the threaded rod screwed into the clevis the only adjustment point.

Thanks for info, advice and tips.

Gene, on the drive shaft coming out of transmission to rear axle there's a brake band there. That's the only place I know of. I have a 2003 Alpine and that's where I adjusted mine. Just don't over tighten. It will get hot going down the road. I'm sure there's a thread in here of more details.

I had a 1999 36' Alpine and the parking brake did not hold very well. Early models used hydraulic pressure from the power steering pump to compress the spring to release the brake. Later models used air pressure. The threaded rod is the only adjustment that I am aware of. I would use wheel chocks to keep it in place.

My 2001 won't hold on hills either. I've had it adjusted and no improvement. I use a chock on any kind of a hill. By the way my test on a hill is to put the brake on, put the trans in forward or reverse depending on which direction the hill is in - if the coach moves I chock.

A couple years ago, this subject came up at an ACA rally "gearhead" session. Albeit on a bit newer Alpine, the aforementioned adjustable brake cable is routed around a pulley before connecting to the spring assembly. The problem was that the position of the pulley was not correct so the geometry would not allow for the cable to be fully tightened--apparently, correct installation of the pulley is somewhat depend on how the factory technician was feeling that day.
As a side bar, if the brake was out of adjustment and allowed to drag, over time this would result in worn drive line brake shoes--so proper adjustment may no longer be possible.

When mine gets to the point it won't hold I'll take it to a clutch rebuilder and have a new surface put on and they can make it softer and put it back on. There hard to find but still around, they also do old tractor clutches and brakes. Here there called A-1 clutch rebuilders.

I'm still confused about adjusting the parking brake.

When the brake is applied the internal spring expands the shoes-the lever protruding from the center of the drum with the clevis and threaded shaft connected to the loose end is pushed upward.

When the brake is released the hydraulic pressure forces the threaded shaft and attached lever downward compressing the internal spring and releasing the pressure on the brake shoes.

IF the spring when expanded is at the fullest extent of its travel it would seem that adjusting the clevis to shorten the threaded rod and increase the upward travel of the lever would not cause the spring extend any farther and increase pressure on the shoes/drum. This would certainly be the case if the shoe linings are worn out. My linings appear to be 3/8 t 1/2 inch thick so I don't think they are worn significantly.

I t has been suggested that there may be another adjustment on the mechanism inside the drum.

Does any one know the manufacturer of the parking brake on the 98 Alpine and where I may find a picture or a description of the adjustment procedure?

Sorry if my description is confusing.

Thanks for the help.
