Want to upgrade the brakes on my 57 oval to dual circuit.
Is this just a case of swopping out the master cyinder and replumbing the pipes?
Or do i need to change anything else. :crazy:
Does the master cylinder bolt straight in?
Thanks :D

Why ?
Straight master cylinder swap will not give any improvement in braking.
Dual circuit master cylinders cost twice as much as the single circuit one.
You'll have a lot of unsightly plumbing to fit a dual circuit fluid reservoir and the feed pipes. But yes, it should bolt straight in, the brake lines are all in the same places.

Isnt it obvious, if one brake pipe/cylinder fails on a single circuit its good bye to all brakes, with a dual system you only lose front or rear.

Yes, it bolts straight on!

I'm interested in the replies to this because I probably have to do the same thing too.
I've got to replace the master cylinder in a 66 bug (oringally a single circuit master cylinder).
As it happens I have a brand new boxed dual circuit master cylinder left over from my previous bug, so it seems like a good idea to use that, especially because it will be a safer upgrade.

So for me it's about extra safety, and I have the dual circuit master cylinder here already.

What's the difference with the reservoir then? Anyone got any pics to show?

My reason exactly !
One of saftey to be shortly followed by a disc brake conversion :D

Wouldn't it simply be a case of getting a complete dual-circuit brakeline set for a torsion bar/swing axle bug and swapping them over? After all, we know you can put a later pan under an earlier body so the floorpans can't be much different can they?
