View Full Version : Routing new brake lines - Corsa setup

Car is going to be fitted with a Corsa servo/master cylinder setup, ATE 256mm fronts and standard drums rear. Need to work out how the lines are to be routed so I can order the brake lines and connections...

The Corsa master cylinder has 2 outlets opposed to the Nova's 4. Is it preferential to...

1) split one outlet in to 2 and for the front brakes, and use the other outlet to run one line to the rear of the car and split it at the back for the drums

or

2) split one outlet in to a front brake and the opposite rear brake, and the same for the other outlet (so 2 lines to the rear) - this is how it's done from the factory?

Are there any benefits to doing it either way? Surely in the event of a brake line/caliper failure it's preferential to have them connected diagonally so you don't lose both front brakes?

Opinions appreciated!

they will be done with fr left & rr right linked and fr right & rr left linked from the factory. if you wanted to fit some sort of bias valve, then it would be easier to fit front to front & back to back. where do the rear pressure reducers fit on the corsa setup?

Iain said no to a bias valve as hes running drums, if it was me id run a bias valve just to have the extra adjustment.

On corsas the restrictor is in the drum mechanics itself iirc.

why not use the nova master cylinder on the corsa setup

why not use the nova master cylinder on the corsa setup

cos it is designed to fit horizontal, not vertical like on the corsa

Also the Nova one has 4 outlets, but still gives me the decision of one or two lines to the rear.

Are you saying I need some sort of bias valve because the Corsa rear drums have one as standard, and the servo will put too much power to the rear?

I think most people run one line to around the fuel tank area, and then split it.

Yep they do, but that means splitting one line to the fronts.

I can't see a better (tidier) way of routing them if I need to fit a bias valve (which I've just found out I do).
