Default Pedal boxes

What are the brakes like when pedal boxes are used? With it being non servo assisted what is the pedal feel like etc? Depending on the route I go with the engine in my Mk1 I might have to fit a pedal box but know nothing about them.
cheers .

You just have to press a bit harder lol.

The one in my 3dr was fine. Good pedal feel etc. was a wilwood with evo 8 front brembos and focus rs discs front, evo 8 rear brembo and focus st170 front discs on the back.

I've got girling master cylinders with ap 4 pot 330mm up front and 300mm wilwoods on the rear and it works well. Stops instantly but you do need strong legs lol.

LOL I was kinda assuming you needed that bit more pressure lads What I meant was what is the pedal feel like for normal driving, does it make it a bit of a pig to drive with having to press harder. IE in busy traffic or say queing on a downhill slope and stuff like that? Anyone know about remote servo's?

Tbh i didnt notice that much difference. My car drove fine, and stopped fine.

Granted i didnt do a lot of town driving but pulling up from a ton was no bother.

If it has the right ratio and the right cylinder sizes then they req no more effort than a servo car.
Mine are very progressive.

Interesting I would have thought it would have been the other way round, can you explain how it works I always thought the larger cylinders moved more fluid and the fronts being 4 pots would need more fluid over the single piston rears.

There are two things to consider when moving fluids, volume and pressure. You need to be able to move enough hydraulic fluid to actuate the cylinders, but, the bigger the cylinder the more you have to push it to get any pressure.
The smaller the cylinder the lower volume you move but the rate of effort becomes less, but the cylinder must be able to move the volume required at the pistons (calipers) otherwise you negate any advantage.
