Volvo 240 Brakes: What is the piston size?

[MrNvgtr]

What is the piston size on the Volvo 240 brakes? My car has them and I need the piston size to properly select the dual Tilton MC setup that Mike_B is making me.

And the question you didn't ask the answer to-

a 3/4" M/C for the Volvo calipers is pretty good...

I have different (1 gen Nissan Sentra) calipers in back, and they

get a 1" rear master.

That works pretty well.

The setup Mike will be going with is full manual, so 3/4ths will be a bit large for the calipers given the stock 4:1 pedal ratio.

Hello Mike,

Does this help you somewhat in designing this setup? I'm building Michaels car and he asked me to forward this information to you but it seems you found what they said. Let me know how I can help, that should help with one measurement!

Curtis,

Yes, the caliper piston size and number of pistons is used in the calculation for determining the correct size master cylinder.

Mike ( - the email I sent you last night with the specs I found on an RX-7 forum, show the diameter as well as the number of pistons. Remember, I have these just on the front brakes.

Thanks for your input guys. We decided on dual 5/8" MC's. This is all kind of guess work because of all the variables involved, so I'm hoping this works out ok.
