There's plenty of room left in the master cylinder for this. The newer 2nd gens (99 up I believe) even had a larger MC put in because of the braking complaints if I remember correctly. If you really want them tight, upgraded to braided SS lines that won't flex when you push the pedal.

Squishybrakesor excessive pedal travel are most likely due to the auto adjusters not adjusting like they are supposed to, or it's possible that flooring the brake pedalona manual bleed pushes the MC seals too far off oftheirnormal plane of travel and the seals get fouled by loose debris. Or possibly a bad bleed job or leak in the system.

If your brakes are squishy, try driving in reverse and build up just a little steam and give the brakes a quick jab or 2 and see if that doesn't tighten them up. That the way the auto adjusters on the drum shoes are supposed to self adjust.Alternatively, you can put the rear axle on stands andadjust the star adjuster with astandard screwdriver until the shoes just rub, just spin the wheel and adjust until you barely hear the shoes rub the drum.

My dad was an automotive engineer. I know all about the reversing to get the adjusters out (first thing I did) as well as adjusting the star until there is a slight amount of rub. Problem is, my backing plates didn't have the hole punched. Another one of those projects in the future.

Hey VW,

I coulda sworn that reardrum brakesare adjusted by using the parking/emergency brake.

Stop swearing.

Anyway, the parking brake will help, but the best remedy is to go in reverese and hit the brakes. It forces the adjusters into action. And, in the old Air-Cooled Volkswagen world, everyone knows that the old VW's have 4-wheel drum and are well versed in adjusting them to barely rub.

Picked up the wheel cylinders tonight, beefy! Got some new shoes too.

If the weather breaks here soon, I'll get them on by the end of the weekend.

from a practical standpoint
replacing the stock 'starwheel' thread rod
with an aftermarket one that has a different
number of acme threads per inch
is a worthwhile thing to do to get the automatic adjuster
to worth slightly better

Well crap,

The cylinders are a 1/4" too short for the 2001. At least that's what the mechanic who's fixing my truck right now said.

Replaced the brake shoes on my truck at the same time. That was a PITA. Used the Passenger side as a template. Took it out for spin, and the shorter cylinderlet the star wheel adjuster move too much, it came loose and it fell off, bounced around the drum, scoring the heck out of it. They're replacing that right now as well as the wheel cylinder.And shoes on the passenger side; those shoes were smooth as glass.

$485 later and I'll be back on the road. Oh well, Merry Christmas to City Garage! Guess I learned my lesson for trying to make a ill fitting part work. Least everybody else knows better now.
