Brake Master Cylinder

Postby claypole1360 » 21 Dec 2011 20:37

Hi there,
I've had my brakes uprated to four pot calipers - AP - princess calipers I believe, I am still running a standard master cylinder, do I need to uprate my Master Cylinder?
Thanks in advance, Calvin.

What's that coming over the hill? Is it a monster?

I think the master cylinder should be OK, Try changing your rear cylinders for 4 speed/auto ones, this helps re-balance the system front to back. ( You'll have to drill an extra hole in the backplate for the locating pin as it's on the wrong side for 5 speed brakes). Then fit some braided hoses in place of the rubber flexi hoses and it should work a treat. [:)]

Hi,

There are plenty of happy owners running Wedges with uprated front brakes and standard master cylinders. If you're happy with how your brakes feel and perform then they're working fine for you. It's down to personal preference.

However, I'm not the only one who found the brake pedal travel excessive after uprating the front brakes. (Bigger calipers need more travel to move the pistons the same amount as before) I fitted an uprated m/cylinder / servo combo when Rimmers were having one of their sales and the brakes felt so much better afterwards. Braided hoses firm the pedal even more to the point of very little travel.

Andy's spot on about the 4 speed rear cylinders and fitting them. They add a bit of extra braking effort to the rear.

Hope this helps,

Adam
