pedal box designing
DIY Si - 24/5/06 at 10:19 PM

Just beginning to design a pedal arrangement. Sorry for the many questions. Anyone know how much travel there is on the type 9 clutch arm? And on a 'standard' brake master cylinder? And what are people using for the pedal 'arms'? 4mm, 5mm, or 3mm channel/box? Or anyone got one going cheap/spare to save me the hassle? Cheers one and all.

Nameless one,

I designed a floor-mounted pedal box some time ago and I based the geometry around the clutch and brake m/c that I already had. Brake m/c vary in their 'throw' depending on their piston diameter (i.e. one push needs to displace X amount of fluid).
Not sure about the type-9 clutch throw - you might have to measure this one yourself at a wrecker's...

Cheers,

Tim

If I remember correctly I designed my clutch pedal to give 40mm travel at the end of the clutch arm on a type 9 box.
I made my pedals from 6mm plate with bosses welded on to take 12mm bronze bushes in the pivots.The brake pedal needs to give the master cylinder full travel and needs about a 5 to 1 ratio.

Would be nice, but looks a little complicated to make in the garage!
