snagger, sorry if i didn'y come across clearly. The landy is a series 3 pick up, LWB 109. it has 11 inch brake shoes in the front. It has a servo. Dual circuit??? i am not sure what this is. How will i know. But to the best of my knowledge there is no fancy valves etc on the brake lines.
Basically there are two seperate issues:
1. during normal driving, when i press the brake, the right front wheel locks. Basically it does not gently stop. eg if i am travelling on a dry dirt road, the wheel will drag when i press the brake no matter how gently i press the pedal.
2. when the landy is laden, and on an incline, the back brakes bind when pressed. I virtually have to reverse to free the brake, otherwise i wont be able to continue uphill.
With regard to failing bearing, these have been renewed recently. Hose failure, how do i test? Will it not be the servo adjustment.
i hope this gives some insight as to my woes.
thanks for all the responses so far guys. i am isolating them one by one.
