Hi All Every so often I get brake failure on my L70 loader. The gauge drops to zero and the pedal has nothing. After a while (sometimes a day) the gauge will rise again and we have a pedal. I think they're hydraulically ran, but wouldn't have a clue where to start. Obviously something sticking somewhere. Anyone got a clue? Cheers Karl
So many electronics on a volvo its stupid. Could be a electric valve somewhere or a wire or a solenoid or you might actually have a mechanical problem. Call the dealer or start tracking the system wires etc and try to find it. You gotta know how those systems work or you'll be lost
What year is your volvo? it could be air over hydraulic brakes in which it could be a simple air problem....
