Hi guys , I an new to this site so HELLO
What i would like to know is :what is the best (and cheapest)way of doing a pedal box,
I am using cortina front brakes and escort MK2 rears

Everybody has their own solution to this. Top mount or bottom mount, home made or bought. Look in the photo section to see what people have done and then make your choice. The Sierra master cylinder works with this combination of brakes and doesn't need the servo, making it an easy option.

Thanx mate , is there a ready made box to take the sierra MC that is proven ?
I went to several shows last year and a recuring problem found by people is brakes :too much pedal travel , wronge amount of presure required, front locking back not working ,pedal hits bulkhead before finishing its travel and more!
what i am after is a working solution to these and any other problems , there are so many sucsesfull builds out there now someone must have sussed it by now !

There have been numerous discussions on pedal ratio and stuff, try reading through the old posts on here. Mine is 4:1 with a pushrod made from an M8 bolt with a female rose type joint and lock nut to give a bit of adjustment. The master cylinder only uses 2 M8 bolts to hold it on so all you need is a braced plate or something to bolt it to, mine is through the 1" box section one side and 1/8" plate the other. The one in a production car will probably only be mounted on 20g. Look at an escort master cylinder while somebody presses the pedal hard and you will see the bulkhead flex even with the remote linkage taking up some movement. My pedals were from a mk2 escort and were cut and some chassis tube welded in to straighten them. If I was doing them again I would make my own from 5mm flat bar as I think it would be easier. As for the brake effort, with Cortina front and Capri or Escort standard rear brakes (same slave cylinders) the SVA reading was good so I left them alone. You can put a regulator to the rear to cut down the pressure (also posted on here somewhere) but if it ain't broke don't fix it's my thinking, personal preference dictates what you do.

yours, Pete

Jasper and I have both gone for Nissan Micra pedal boxes. He's got the MKII Micra and mine is the MK3 which has the benefit of all three pedals being separate units.

Didnt try to work out anything with my brake pedal, just cut down the Micra one to make it fit, then mounted the Sierra cylinder in the appropriate place. Bled the brakes last week for the first time and it all seems fine, time will tell....

Bear in mind the MK3 at least is a bit of a bu##er to remove. With atleast one hidden nut at the top left of the brake pedal.

Admittedly the one I was getting it from was the third car on the pile and to get it I had to spend an hour balanced on the brake hub of a car on the next pile and the open window of the one below but still!

HTH,

James
