Hot Rods Disk brakes for T-bucket spindle mount wheels?

Maybe look into laser cutting for the rotors but you would still need the center register diameter and the OD machined as well as the bolt circle. Lastly Blanchard grinding to size and true up the rotors. Not cheap but how bad do you want to use them?

 

maybe easier to find some others(maybe foreign) that just require minor machining to fit?

 

I think @1biggun is looking to replace rotors like these, steel, .375, Blanchard ground. In the past PSI, Super Bell, Wilwood and others produced kits with rotors like these.


I have this old PSI kit with Airhearts on my coupe.

 

Yeap I have several sets of those or similar . one set has some rare Rotors with 500 on thme there was a thread about them .

The Ghia Calipers are not a bad set up for a light car with narrow tires .

I may try to use one of my set ups on a T with a 4 Cylinder .

25 years ago there were a lot of kits with aluminum hubs sold . Speeedayw used to say how you do not want big heavy Cast iron rotors and hubs on a light car .

I recently used some Nissan 280ZX turbo rear rotors I tuned the OD down to clear the smoothy wheels I made for my A PU that got a non HAMB approved custom made IRS form a about 10 different cars. ( Sorry but its staying in for now it would brake my dads heart if I yanked it hw was pretty proud of it and does work really well ) Any way
The rotors were solid and fairly thin and were ford 5x 4.5" pattern but could easily be redrilled . for other things they were about $25 at Rock auto . they were about 11.25" but I turned mine down to about 11" I was thinking they would maybe work on a normal rear end or even a front hub . I stored the in my mental data base next to the Suzuki samurai 5 on 5.5" front disk that would maybe fit a early ford front or rear . there stepped so would not work on a spindle mount but I spent a week on Rock autos site that has dimensions looking at lot of Nissan and Honda disks that are 5 x5.45" pattern

There are a lot of motorcycle disks I think could be adapted to spindle mount wheels.
some of those touring bikes are pretty damn heavy . Some were I saw a set of wires that had a addapter that took the old 4 bolt disks and made them work what I think might have been Harley disks for early sportster that were a bit smaller OD .
I know MY 77 XLCR cafe racer had a pair of them that looked very close to what I saw . there were solid not drilled but motorcycle rotors can be drilled I used to do it all the time as there not cast . In fact back in the 80's I had a drill guide I made for doing Honda 750's for guys .

 

What exactly is Blanchard grinding/ I have a lathe that will handle these but never seen a set up on how there ground .

 

Depending on the size of the grinder (Blanchard is the name of the manufacturer) a Blanchard grinder has a rotating table that has a magnet that can be energized, the grinding wheel can be raised or lowered to accommodate parts of various heights. They are available with different size tables and wheel size. Non-magnetic parts can be blocked in place with any ferrous metals and also successfully ground. In the case of those rotors one side is ground and they are flipped to finish the other side to the desired thickness.
