Hey again,I am almost done with the Granada disk swap.still have to swap the master and regulator block.it went pretty smooth just had to fab up flex hose brackets.i took the drum hose and ground off the crimp at the mount end,and took a ford pickup bumper mount and cut the ends off it which had the right size hole already.then welded it the factory mount,didn't even have to shorten the brake line.one question I do have is the locations of the lines on the regulator block any help would be great thanks!
You shouldn't have to change the junction block. If you got a proportioning valve from a Granada, the bias will be wrong for a Maverick anyway. The BEST way to do this swap is to get the front hard lines and flex-hoses from a disc-brake Maverick.
I had drum brakes before I think I definitely need to change the block.going from a wheel cylinder to a caliper is a huge bore difference.
I never changed mine, and the system works great. It's true that the rear wheels will lock up sooner, which you need to be aware of so it doesn't take you by surprise, but if you are running taller/wider tires in the rear, it compensates for that.
I have no junction block or proportioning valve. mine are plumbed straight from the M/C to the calipers...Disc/Disc
