with 2 sets of calipers would it not create more heat with the improved braking and with more of the disc 'covered' with calipers less area for the disc to cool?
must admit it would look the dogs B's but i reckon if it was do-able it would already have been done
I think the biggest issue will be that the master cylinder is set up to move the correct amount of fluid for 4 calipers in total. Adding another pair to the front will need a bigger volume of fluid movement, which will require a longer stroke or a larger diameter master cylinder bore. Without a bigger bore you will need more travel on the pedal to give the same excursion on the brake caliper pistons.
Also, the pressure on the individual caliper piston will be reduced, meaning less braking effort at the wheels.
Yep, that's what I meant about displacement. Shouldn't be too difficult to fit a bigger master cylinder.
I say fit two So, in effect, it would be two systems, that way you could connect the new system to a big, huge, red button on the dash that reads 'ONLY USE IN EMERGENCY' (or better yet one of those 'BREAK GLASS IN EMERGENCY' fire alarms)...the button would have to strobe ominously either way, of course!
Strobe or "Throb"?
Plus having a second caliper mounting onto somewhere, I'm assuming onto the original caliper mounting point too?
I would be very twitchy about transferring more load onto that point, it will be designed for one caliper and fitting a second will double the forces going through it, maybe overloading the casting or the bolts.
Also the extra heat via increased friction into the disks building up faster than they can get rid of it. Then you need bigger disks to give a bigger surface to dissapate the heat more efficiently.
