pedal box

[Konrod]

Hi everyone. When I last went to le Mans classic in 2018, my brake lights failed, turned out the "normally closed" pole had failed, but by finding a scrapyard I got hold of a normally closed relay and was able to wire up the "normally open" pole of the switch to get me home. That kludge of wire and electrical tape of course was still there 2 years later - if it isn't broken........

I also have a pair of the curved pedals to fit, so last night I thought it was time to replace the switch and fit the pedals. The switch was changed, which was the short version - the long version included swear words as it is a bh of a job. It is like being James Herriot with both arms up the a**e of a cow and needing to get your head in as well. I am "generously proportioned" (my wife is less complimentary) which didn't help. of course, when I got the old one out both poles started working

I didn't get the pedals done. My idea before I'd really looked was to disconnect the rods and unbolt the clutch/brake cylinders and just remove the frame. Looking at it in the cold light of an LED inspection lamp down a long dark footwell, I couldn't see how you can get the pedal frame out without having to disconnect all of the brake and clutch hard lines as the brake servo and clutch master cylinder are mounted at an angle on the back of the frame.

Please tell me there is a way without having have to disconnect the fluid circuits to get the frame out as I have no chance of reaching the union block well enough to unbolt the copper unions, and the mess of fluid will be epic.

Regards

Somebody did this last week. Posted up some pictures. Can't remember whether it was here or facialachne.

There is as the master cylinders bolt on to the back of the pedal box, so once the pushrods have been disconnected the pedal box will come out without them.

It is a pain though as the nuts and bolts aren't captive so you need both hands. If you thought getting the brake light switch out was a challenge....

The biggest problem I had was freeing the four nuts underneath the floor that hold the pedal box to the chassis. The bolts are attached to little plates that shouldn't be able to turn due to being up against the sides of the pedal box frame but mine were that rusted up they ended up bending the frame and turning, so I had to cut them off underneath.

I tried to do this last week and failed. I managed to undo all the floor fittings and 5 of the 6 bolts holding the sere off/master cylinder but just could not get on the bottom right bolt under the throttle pedal. Much easier to do with the seat removed. If you are going to try it get that bottom right one out first.

Thanks - I assume therefore that the servo/master cylinder will push forwards of the frame? I was concerned that the hard lines would not have enough flex.

I'm also concerned that I will need a cave rescue team to get me back out........

Once you unbolt everything the pedal box frame will slide out leaving the master cylinders where they are. It's a fun job!
