High gear and parking brakes

Post by thom » Thu Sep 12, 2024 4:20 pm

On our '21 Touring, it has got to the point that I have to hold pressure on the lever with my left foot for high gear to hold. And the parking brakes, with aftermarket, lined shoes don't hold very well. I'm hoping I can adjust it and make it work but I am unsure what to try first. Shorten the rods? Lengthen them? What say ye?

Disconnect the rods & check your clutch linkage settings. The brake lever must stay all the way forward when driving or you risk burning/slipping the clutch. The rods act as too long. Since you added aftermarket brake shoes, it could be the lining is too thick not allowing enough cam lever free play.
If you didn't have to do a lot of grinding to fit the shoes, they are not correctly fitting in my experience. It could be as simple as the lining edge tight in the corner radius of the drum. Look @ brake cam lever movement range @ both sides.
The parking brakes should be activating with a past vertical lever or later while having a free neutral. With the lever about vertical you should be able to easily push the car.
