Why is Hydroboost Installed at Angle in Mk IV?

I installed the Hydroboost from a 2001 Mustang Cobra in the Mk IV using the FFR mounting bracket that has a notched keyway that mounts the hydroboost at an angle (see attached photos). The notch obviously keeps the hydroboost from moving; however, the angle can't be right. Does anyone have experience with this? Thank you for your help.

I can't answer the "why is it that way?" question, but the '01 hydroboost is mounted at an angle on my Mk 3.1. It looks just like yours. It hasn't been a problem for me and I have almost 10,000 miles on my cobra.

That's good to know. I debated using power brakes since the car is so light. Are you glad you used power brakes? Is your steering manual or power?

My cobra is a donor build and uses the 2001 GT master cylinder, front and rear calipers and steering rack. I kept the power brakes since the Mustang m/c and calipers are engineered to match as a power brakes set-up. I kept the power steering since the rack ratio is more suited for power steering. I did not use the stock Mustang brake metering valve/proportioning valve/distribution block (whatever you call that thing) and have no issues with brake bias. I'm happy with my choice of power brakes and power steering.

I had the same question. When I did a tour of the factory in 2005, they had a hydroboost equipped Coupe chassis in the showroom and I asked about the angled mounting arrangement. I think it was either Mark Weber or Dave Riha (can't remember) that told me it was to provide adequate clearance to remove the MC cap. If it were mounted in a more standard orientation, you might not be able to get your hand under the 3/4" tube to remove the cap and it would make filling it even more problematic than it already is. It's not all that visible once the body is on in any case but I opted to use a remote mounted reservoir to make filling simpler.
