Confused With Master Cylinders
Im totally stuck on master cylinders
I currently have a sierra one that used a servo but im being told its too long.
I looked at the compact wilwood ones but firstly i dont know which size and secondly they only seem to have 1 connection (where as the sierra has 3 (2
fronts and a single rear)
on the single connector ones do I just T piece the pipe more?
edit to menition im running wilwood powerlites at the front and standard sierra dics at the rear

with the willwood items you would usually have two items, one from rear circuit, and one for fronts complete with bias bar. i dont think you will be
able to 'tee' with one master cylinder as i sure there is a rule about separate circuits for front and rear

For fear of hijacking the thread, I'm having a similar dilema. Not sure whether to go for reconditioning the sierra one I already have, or as
MikeFellows says, go with something else 'cos the sierra one is not suitable.
Running standard 9" drums on the rear (live axle) and cortina discs on the front.

DDLL - that is my setup (9" drums, with stock M16 cortina stuff up front). I use a 0.75 for the fronts and a 0.625 M/C for the rears, with a
balance bar to get it just so. I have found it really hard to balance the two, as the 9" drums are really very effective.

Ooops, I think I meant the other way around. I'm just pleased it works, as changing them once the car is paneled is a right PITA!

Just to show my complete ignorance, how does the balance bar fit into the system (i.e. a diagram please )

Just read the write up from the link, the pics are good and worth noting the brake light switch set up, which I am trying to convert from the fluid
push system to a micro switch. The one picture that is missing is how to mount the switch to the brake pedal......dohhh!!!
any one got any pics as I don't want to drill to many holes in the floor to get it right.....

If you want to use a single master cylinder I believe one from a fiesta without servo gives good results.

I keep reading that it requires too much pressure to get the car to stop due to usually having a servo?

Loads of people have used the Sierra master cylinder without any problems whatsoever. Whilst there may be more efficient brake master cylinders on the
market, the Sierra one is quite capable of stopping a seven without a great deal of effort.

Agreed BUT not all people have the same feel for the effort required. I for one would like to "feel" that the car is more under control
under braking. My son says he can "feel" how much the car is slowing ,but for me the effort put in does not relate directly to how much I
"feel" the car should be slowing.
Also if you have sierra parts all round then obviously the system will be better balanced as it's a proven setup.
I have cortina fronts with M16 calipers and fiesta discs at the rear with golf calipers which may or may not be a bit of a mismatch for the sierra
cylinder. So yes they do work Phil but some of us are looking for a "better feel to the pedal"
If it looks wrong it probably is wrong.
