Hello all. I have just replaced the brake master cylinder and wheel cylinders on a 66 beetle and bled the brakes. The pedal is firm to start with and everything is ok. I walk away and come back later and the pedal goes to the floor. If i pump the pedal it gets firm again. Bled the brake system several times and still the same thing happens. What am i doing wrong. any help and advice would be greatly appreciated

Try adjusting the shoes again.

I read it on samba, so it must be correct.

Sometimes Volkswagen dealers sell spare parts. Amazing isn't it!😂

yep adjust the brake shoes

make sure you start bleeding on the rear passenger side first then go to the drivers side rear then front passenger side and finally front drivers side
