Quick master cylinder question
« on: 18 May 2011, 21:29 »
I'm in the process of putting slowly my brake system back together. Want to double check before I go much further



I have two M/c's OEM on the left and eurocarparts(ECP) one on the right. 2 ports vs 4 ports. How do i hook it up? Tried putting some fluid through ECPs one and it comes out top left and wee trickle out the bottom right one (even with the bleed nipples out). Would that sound about right? and does it matter which circuit I put them on?

Thinking I might use the ECP as the seating for the reservoir is a lot less corroded and rubbers are seated better.

Move the bleed nipples to the ports you won't be using and just hook it up as before.
Just because you're offended doesn't make you right.

Any idea if there will be a difference in pressure? By that I mean more pressure coming from the front port of the M/c than the rear port and thus i need to put that line to the front brakes and the less to the rear brakes?

Do i need to run a seperate line to each wheel and hook them up to the individual wheels?

Cheers

Your braking should be diagonal split, so there should be two ports in use, unless you're planning on doing something non-standard with it?

If you are going to move away from the OEM set up then you can put a separate line to each front wheel and a single line to the rear, with a reduction valve in it. 

The pressure in the system is equal unless you do this, so it doesn't matter which port the lines come from.

I see. That clarifies things somewhat. I'm not planning anything really non-standard with it, the only thing I've done is fit 280mm discs/ calipers off a G60 Golf.

I'll see how i get on tonight. Fingers crossed it stays fair and that the thing actually works this time.

Thanks for the info  :smiley:
