Question
I have a Tilton pedal set and I have been told it was a bad thing to have two different bores for the front and rear brakes. I have a Triumph TR4 vintage racer and the plan was to use a 3/4 bore on the front and a 5/8 bore on the rear.
Please advise,
jg

Hi Jim:
My first race car was a TR-3,   I still have pictures from 1960 .

To answer your question, if you have the Tilton brake bias cable, knob and balance bar between the cylinders, the bore shoudln't matter since you will adjust for proper balance anyway.

If you DON'T  have the balance bar you will have more pressure exerted on the fronts which may be what you want, or it may not. I'm not sure I like the idea, and I'd be careful entering the first few turns with it. If you have trouble keeping the back end behind you, it wasn't a good idea .

Most Tilton setups I've seen use two of the same size with the balance bar and associated stuff.

Let me know what you decide and the results .  Write to DanL5454@aol.com
