M/C and calipers (simple question)
 

Do single pot require more fluid than 4-6 pots to engage the rotor?

I figured I'd try and use the stock dual M/C first but was wondering if this is true I thought it would be the other way around.

I guess its not so simple

Yep not so simple..

This is a debate that is currently going on.. There is a recent thread that talks to this.. and is worth the read..

OK I have been thinking about this. You could probably figure it out mathamaticly by determining the volume of fluid required to move the piston (s) the required distance to apply pressure on the rotor. Also take into account that the single piston calipers need to move the non piston side of the caliper also. I will try to work on some numbers tomorrow if I can. But in my own experiance (motorcycle) the 4 piston calipers require less lever travel than the sliding calipers.

well i read another post that said the same thing that I did, actually sort of cut and pasted the sentence in form of a question. Just wanted to see if it made sence.

Either way thanks, as I figured that best way will be to try and see what works for my style of driving and so forth.

thanks

Hi

I have just gone backwards (sold my car), went from 4 pots all round back to stock front disks and rear drums, both used stock 19mm MC, I cant believe how spongy the pedal is with stock brakes, not to mention the lack of retardation.

The thing to get your head around is that your not moving a hydraulic ram, your just applying pressure otherwise every time you applied your brakes the fluid level would drop and come up when you released the brakes.
