    Hello,



    I have a 1989 Hymer B694 Tag axle motorhome on a Peugeot J5 2.5 td chassis.

    We had a problem with the brakes as every time you pressed the pedal the brakes would lock on, After much investigating we found what looks to be a one way valve just back from the nearside seat, When we removed this and put a spacer in its place and the brakes have been ok since if a little bit more travel.

    Can you confirm our suspicions as to why we need a one way valve in the system?

    It may be acting like one, Im not aware of any one way valves in any braking system Its more likely a pressure regulator/equaliser brake bias valve thats gorn tits up it needs replacing dont circumvent anything on your brakes some very strange things can happen under emergency braking, your insurance will have a field day if police examiner says system was modified:Sad:

    I'm sure Geo is right its a pressure regulator/equaliser brake bias valve especially as its a tag axle. Seem to remember reading about these playing up when I was researching mine before I bought it. Tag axles often need a double tap on the brake pedal to increase brake pressure. Mine does and plenty of others I've spoken to have said their's are the same. Brakes work perfect without a double tap and fly through the mot but pedal pressure definately increses if you just release pressure a fraction the reapply.

    Hi Jim,

    Tried them, They seem to only do interior work.
