Brake info
Posted by: westpismo ()

When I purchased my 63 Monza, it turned out the brake shoes were not put on correctly (some wheels had two forward shoes, some had two rear shoes etc). So installed all wheels correctly and adjusted all brakes. But they still didn't feel great. So I have since replaced the master cylinder and wheel cylinders. Lines seem good. The brakes certainly seem to work better better, but it's been a while since I have driven on non-power drum brakes. I just don't know how they should feel. They catch pretty well to slow down, but it takes a fair amount pressure on the pedal to come to a full stop at driving speeds. Is this how it the brakes should operate, or is there something else I should be fixing/replacing? Thanks.

I will guess that 'westpismo' is southern Calif? If so there are Corvair clubs plus shops around you. Join your nearest club and ask for a comparison by another owner. Run by one of the shops and ask for their opinion.

Good luck and welcome to CCF

If by lines you're referring to the rubber brake lines, you really can't judge lines by appearance, they fail internally, usually by swelling and restricting flow of fluid. If there's any doubt change them out.

I am also thinking that if you moved/rotated shoes from one drum to another, the shoes are out of "arc"

That is some drums have been recut more than others, and the shoes wear in to their respective drum. Then you moved some of them, and now they need to "reseat"

What is happening is some of the shoes are not making full contact with the drums now.

But I would replace the hoses for sure, like mentioned above.

Vairs don't really like long life shoes as they are a harder compound and require more pressure than the less expensive softer shoes.

I judged the metal and rubber lines by the fact that, after installing the wheel cylinders, when bleeding the brakes (2 person) all lines showed good pressure and flow.
The notion that correcting the installation of the shoes (and adjusters etc btw) may have affected the contact of shoes and drums makes some sense, however.

You can also decrease effort by installing a Master cylinder for metallic has a smaller bore and gives you more pedal power!

Standard is 1" bore

Factory Metallics got a 7/8" bore
