Viva GT: pedal box modification
Its going to seem massivly backwards, but today the steering column and the pedal box were stripped from the GT. There are a number of jobs that have stacked up and require this work doing before I can move forward.
1. The steering wheel is too close to the dash, so I want to adjust things as much as I can on the column links to lift the steering wheel away from the dash.
2. The brake and clutch lines from the master cylinders to the fill pots need making up.
3. The steering column is too close to the clutch master cylinder.
4. I dislike the silver panel in place of the old master cylinder outlet.
5. I need to redesign the bias adjustment, adjuster.
Todays work is more about strip down and tackling item number 2.
With the pedal box out of the car I could see there was an opportunity to run the brake lines out through the old master cylinder hole. This was done with some reshaping of the hole in the pedal box and carefully drilling the silver cover plate.
You can see below the silver plate has been bolted to the pedal box (so no longer sealed to the firewall), and three black AN-4 fitting placed in position. The silver plate will be painted black to better suit the engine bay before re-fitting.
Once the panel location was finished, the fittings and 90 degree unions, needed some trials in order to best position internally so that the brake pedal is not fouled.
The image below shows the nearest union clears the pedal arm by 5mm, and the outer union is well clear of the throttle cable. It’s all tight but manageable.
Tomorrow’s job is to make up the braided lines and attach them to the pedal box in such a way as to stay clear of all the moving parts, I have the routings basically worked out and hope to have the pedal box back in the car by end of play tomorrow.
I also mentioned in item 3, that the clutch master cylinder is very close to the steering column, luckily for me Willwood have a lug on the end of the clutch master cylinder so a little Dremel and a file later has sorted the clearance issues.
The bias adjuster I am still considering how best to make dash adjustable, I am sure an answer will come to me? A stock cable adjuster will do, but if it comes out to the right of the box it may foul the throttle cable, if it comes out the left of the box it potentially fouls the clutch arm. Much to consider. First get a cable second work the problem.
