hi all help please ! could any one tell me if its ok to have the servo/ beake master cylinder lower than the front calipers im having trobule to get the servo and stearing collom in thanks

hi mate as far as iam a wear as long as the brake fluid reservoir's are mounted high for the air to escape you should be ok

I heard a lot of moaning here about getting a good pedal on a 7 build so I went for top hung pedals using Sierra bits with the master cylinder above the top rail of the chassis. from there I ran all brake pipes downward to calipers and the back axle. I am pleaqsed to report that this set up blead through by gravity in 5 mins and took about 2 strokes of the pedal at each bleed nipple to get a rock solid pedal, that's the fastest and easiest brake bleeding exercise I have ever done! So get gravity on your side and you will be OK.

Do you really need the servo?

No, you will lose all feeling in the brakes

do you think id be better off with out a servo ?im running a 1300 crossflow and thanks for the replys so far

I've got a servo and it's mounted lower than the front calipers, although only just lower.

You won't loose any feel.

I'm also a professional engineer who designs brake systems for a living

Just want to suport what Jag is saying about servos . I have one on my car and it works fine and as I have a some what shorter peddle with less leverage than the original , still the effort required and the feel are both good.

Speaking personally a servo is the last thing i would want it robs the pedal of all feel and introduces unwanted pedal travel and spongeyness, but drivers of modern cars are so used to grossly over servoed brakes that they would find the brakes on most Seven replicas take a lot of getting used to.
Seven type car although very light because of space restrictions is a bit short on pedal leverage ratio so the pedal riquires a good bit more effort pedal than the average tin-top.
