Epic machine. I miss my 850 T5

Had a read from about page 250 there some very good work has went into this, lucky in that last video I would have needed a change of trousers after that. Keep up the good work

Thanks mate appreciate the comment.


OK so I had my brakes set up roughly working, but it wasn't a great pedal feel again. I had to address the pedal ratio problem.

Old pedal assembly out:



Now we all know the issues with fitting a standard Corsa pedal into a Nova;



What I really need to do is straighten the pedal, and move the pivot point up on the housing, resulting in a longer pedal and better pedal ratio:



This is achievable since the pedal box rod is a lot smaller than a standard Corsa rod, so for max tweaking I got a selection of clevises (aftermarket, Nova and Corsa ones)



Needed the longest possible in the end:



This looks like a bodge job but it's all strong and safe, and is in fact the second one I've made (did a prototype version before this for testing)



Difference to standard:



Needed adjusting down on the clevis in this pic, but it all lines up fine:

The other problem I had was the rear was constantly locking up no matter what I tried, so I've swapped the .7 rear cylinder out for a .75 one:



To save cutting another down, I've swapped the push rods over:



Just need to remove the small circlip:



And the eagle eyed have noticed I've removed the pedal switch holder, so I'm now running a bolt that replaces the banjo bolt on the front master cylinder, that operates the brake lights circuit:



And it's got a new windscreen due to a few chips in the old one:

Nice bit of re-engineering there. Like the banjo-sender too. Keep it up

I thought you were meant to be working from home not updated your car thread?!?

[Benn]

Love the pedal work.

Can you index this thread please Iaiyn. I'm tired of searching through it to steal your ideas.

[Iain]

Gotta earn the theft by wading through 300 pages of waffle.
