Garage / Re: front brake lockup
« Last post by EuropaTC on Today at 11:44:36 PM »I can't answer the question on proportioning valves and what you say sounds logical, but rather than guessing I think I'd ask Willwood for their comments.
The braking balance as standard is generally praised in dry conditions, it's wet roads when the real problems come along where you don't get the weight transfer. The snag with deliberately allowing the rear brakes to come on first is that you could end up with the rear end locking so you'd be swapping one problem for another. And of course you'll only know that on a wet road with a panic stop....
One thing I would add is that if you increase the piston diameters is that you'll also increase pedal travel, more so if you managed to fit larger rear cylinders. Not a deal breaker, but something to consider when re-designing the system.
In the UK, ANG classic cars list the type 12 pistons, I don't know if it's an old listing and they still have stock but it might be worth an email.
