GT Brakes 2017
This post is about rebuilding of the pedal box, which shouldn’t of needed to of been done as when it was made for me (before it was given to Retropower) certain assurances were given about its quality. Alas things are not as they first seemed when it came to bleeding the brakes. The clutch master cylinder was nice and shiny on the outside but full of rust on the inside. Both brake master cylinders could be the same size, so I am swapping the lot out.
So We have had to strip all the electric steering back out of the car, in order to get access to the pedal box. Then remove the pedal box in order to get access to the master cylinders.
Cut a long story short, I ordered some new master cylinders to replace the old ones. Time for shopping… 1 x 0.625″ and 2 x 0.75″ master cylinders later. 0.625″ for the front and a 0.75″ for the rear, having taken advice from people I trust for advice.
So after stripping the old cylinders out and inspecting them with my fears confirmed it was time to retro fit these one onto the pedal box. Another issue showed itself up during the rebuild, the bias bar was seized, and had to be stripped right down and lubricated, its now all back together and the bias works as it should.
Yes I know the desk is messy (I admitted today that we need to spend a day tidying the workshop, as stuff is all over the place now, I am not used to having the luxury of putting things down and leaving it till another day, now after a few months of another day, stuff is everywhere, My bad).
So now the pedal box is fully built up (bar a brake light switch) and re-installed back into the car, the pipework all reconnected. So it was time to bleed the clutch. Pervious attempts had failures, this time it was almost bled in a few pushes! I think its done now, but my god is the clutch heavy! I will only know the real effect of the heaviness when I start and attempt to move the car. (it could just be the bearing is stiff on the input shaft, and some lubrication is required?) The steering will need to be reinstalled but not until the brakes are all bled, which is the next major task for this year.
