i have a problem with the drum brake from my ford mondeo (1993). On the
brake test stand the brake power of the right back wheel is nearly zero.
So I have changed the brake shoes on both back wheels. But without
success. So I have changed the brake cylinder of that brake. Nothing
happens. During the bleeding of the brakes the flow of the brake fluid
was normal, so I dont think, that there is a problem with the brake pipe.
Tests on a sandy underground shows, that all wheels are blocking, except
the right back wheel. But when I do the test with the parking brake,
both back wheels are blocking directly.
So I think, it has something to do with the hydraulic, not with the
Is it possible, that the brake pressure reducing valve is out of order?
Or can it be, that the main brake cylinder is faulty?
Any help would be appreciated.
Kind regards from Germany,
P.S.: Sorry for my bad english. I have the technical expressions from a
technical german - english dictionary, so I hope, that you understand it!
