Brake master cylinder question (Lola T492)

[Daniel Thompson]

What size master cylinders are typically used on a car with LD65 front calipers and LD20 rear calipers. I want to get the best size the first time...

[Tony Sleath]

When we had a Swift DB2 in the 90s with those same calipers I used a 13/16 front and 3/4 rear.

Just checked a Royale in the shop with those calipers and its 0.7 Front and 3/4 Rear.
No balance issues that we are aware of!!

Phil,
For most, I think you will find the .70" bore a little small to push four 36mm pistons and not have a driver unhappy with the long pedal.

What can I say! no complaints from the customer so far but you are probably right. He has bigger cyls on his DB2 with LD65s all round.
