PEDAL BOX - current flavour?

[Greg Rust]

Yea I had to bend up some flat bar and make a bracket to mount the switch.

Can still use a normal switch if you want.. but its just more clutter and shit where a pressure switch banjo bolt is neat and tidy and out the way..

old shitty setup from back in the day...

Allright so been trying to order one for a month, summit wont help me choose brake master cylinders and keep referring to contact tilton. Wh have only replied to one of 4 emails despits them quoting 48 hour repsonses, and have simply suggest a base cylinder to start with and told me to test that and if its not suitable try a different one.

SO who can help me choose brake master cylinder sizes?

[Greg Rust]

Dattoman will be in here to help you out, he loves brake shit.

There is no single answer....
Quite a number of factors will determine what you use, from caliper piston sizes, number of pistons, weight of the car etc etc etc
Most times ppl just say go with a 1" and 7/8" for the brake and 3/4 for the clutch but whilst it may work it may not be ideal.

what if im able to provide all that information?

"you can use this as a starting point-try a ¾” front and a 13/16” rear "


thats the best i could get out of them after a month

Dealing with the wrong people then.... when i was confirming what MC to use as i have 2 of every size AP Racing MC's I sent off an email to AP Racing/Competition Friction with my info and got my reply that day.

What brand MC's are you going to use?

This is one of the best brake calculators ive come across:

Helped me diagnose the lack of front braking performance i was having, and is generally good. Remember its in imperial.

tilton short stroke master cylinders, the ones to match the tilton 600 floor mount box

Default MC sizes for a typical 5 to 6:1 leverage ratio balance bar are 5/8" front, 3/4" rear, 3/4" clutch.

This has been the rule for at least 40 years.
Edit For front engine rear drive tin tops.

Those big masters sound like someone imagining a single or tandem 3:1 boosted system being set up.

if you want a gun set up look at front pivot masters; 77 Series Tiltons.

Momus, that's what I started with, no idea yet if it works but a good starting point.

Have a look at all the yank sites discussing M/C selection..... im not sure how they came about it all but then theres not much i get about them when it comes to cars :D
Never said its the rule, just the bs generic answer ppl give out..

on the Super Tourer, it uses a .7 upfront and 7/8 on the rear..

[Momus]

What is the Supertourer? Front drive?

Dont fack about guessing master cyl size etc. If you can come up with all your braking system info, I've got a spreadsheet that will calculate what you should be starting with. Only real assumption you need to make is vehicle COG, though that can be measured if you're keen. I made the spreadsheet up for my car so I could order the right piston size in my calipers. Worked well, but is no guarantee you will nail it first time. For instance I've just changed from 5/8 masters to 11/16 masters to reduce pedal travel. It did that, at the expense of harder pedal of course. I wanted a softer pedal to get car registered initially, but turns out I only tend to drive on the track, soothe shorter harder pedal is the better compromise. You'll only find out what suits you by experimenting untimately. BTW, I used wilwood pedals. Seem to work fine, but I have nothing to compare with in my experience.
