The stock car came with a nice stamped steel heat shield to protect the master cylinder and reservoirs from exhaust manifold heat.   You can see it above in this picture of the engine in the Corolla I used to race.

While the red car has a ceramic coated header on it — which helps – I still wanted to shield the M/C.  Unfortunately, finding a used OEM piece proved impossible.  So I set about fabricating one.  Started with a piece of relatively light sheet steel.  I’d have preferred aluminum (reduced mass = less re-radiation), but we’re deep in the middle of isolating from the Coronavirus crap and I don’t have any sheet aluminum big enough in my pile of parts.  I was really happy with the bend – used my 5″ bench vise brake – and just worked the piece from side to side bending a bit as I alternated.  Came out perfect – and I got the angle right on the first try!

There’s a captured nut on a small bracket on top of the booster — I figured I’d use it along with the master cylinder retaining nut on the same side to attach the shield.  Made a few bracket pieces out of the same sheet metal.  And used the brake to bend the brackets.

Once happy with the positioning, I tacked welded it.
