Brake pedal return spring

  1. Hi folks

    I am struggling with the above!

    I'm just in the middle of fitting new steering and suspension and noticed that the main brake pedal return spring had broken and was doing nothing, so thought I'd replace it.
    I removed the clamping bolt but it come off the shaft, there is still rotational movement but there is no lateral movement and with the chassis being in the way....
    well how does it all come apart and what has everyone else done?
    I have added some pics so you can see what type I have and what it looks like, has anyone got any ideas on how I can open up the clamp????

    Thanks in advance, you wonderful people.

  5. Hey thanks for the replies.

    I am sure that the shaft goes to the right (on the pics) I think that it is actually towards the passenger side.
    as the arm that acts on the master cylinder is welded on and the pedal arm is clamped, but cant get that clamped arm off GGrrrrrrrrrr!

    anyway....
    I was just wondering is there any need to fit the round spring? is there any reason I cant fit a straight spring, I was thinking on the master cylinder side and pull forward to the front of the van.

    I appreciate that this would not be stock and would upset some of the purists, who I do respect and would love to have a stock van, however I have just fitted a Red 9 design front end, so I don't have a stock van anyway.

    Thanks

    Matt
     
  6. have you tried a puller on the other end?

    @PIE says a lot of vans do not have them or they are broke ,the pressure/spring for the m/s pushes it back ...
     
  7. Just taken this off mine today . the shaft slides out towards the passenger side , mine was very tight and I used a long blunt cold chisel to knock the pedal off the shaft then punched the shaft out .

    I have just done mine it’s a right pig.

    It needed a good beating I used a metal bar as a drift and a big lump hammer to get it moving

  10. Just recently done mine and as above a nightmare job. Lots and lots of heat, solid punch, sledgehammer and lots of swearing needed! I used the punch through the chassis to hit the shaft out of the clamp if that makes sense.

    As above shaft moves out to passenger side. Split in the clamp does not go all the way so no easy way of opening it up slightly. Almost resorted to cutting the split all the way through to get it off and welding it back up afterwards! Don't think this would have been a problem.

    Mine just had an old mower deck spring from the master cylinder push rod to front of van for many years, just seemed to make sense to replace it whilst completing the restoration. It did cause problems with no spring, but can't remember what they were as so long ago!

    Wow this is a first for me. I did this job at the weekend. I slid the clamp bolt out and prised the arm off the spindle with a big screwdriver. No heat. For once my bus went easy on me.
    Sorry I don't mean to gloat but everything else I've touched on this bus has fought back like a banshee.
    Just got to buy the new spring now.

    I wish mine was easy Mark.
    Maybe ive been going at this the wrong way...
    Ive heated it ok but ive been hammering the arm towards the driver's side (rhd)
    Today ill try punching the pivot through the chassis hole.
    Cheers guys

    Ive been battering this most of the day...
    WD40 leave for an hour then repeat...
    Its moved about a centimetre i can see the splines but its still fighting me.
    Ive put a plastic bag tightly around it and filled it with WD.
    Tomorrow its off i hope

    WD40 isn't a penetrative fluid. K2 Vulcan is good stuff. But if it's move a centimetre I would try levering it the rest of the way - I found that once mine had gone about that far I put a large open ended spanner at the other end around the spindle in the gap that's opened up to help support it if that makes sense. I found the constant lever pressure worked better than a clout. Keep at it, you'll have earnt a beer when it comes off.

    On Thursday i encased the whole thing in a plastic bag then filled it with Wd40
    Then this morning i joined two long socket extension bars together stuck it in the end of the shaft and kept wacking it with a lump hammer.

  19. Its satisfying when it does finally drop off isn't it!

    Well done. One of the more challenging jobs I've had lately.
