[urq] Brake bleeding

[ANTHONY ATTARD]

Good morning,

I replaced the brake master cylinder on my 83 Ur Quattro because it was the original. Unfortunately the pedal was not what I considered to be a hard brake pedal by today's standard. Anyway, after replacing the B-master cylinder I hoped I would get a harder pedal. But It did not turn out that way. 
I bled the master cylinder on the car, but I did not bleed all four corners. I did not think I needed too. Does anyone have any advice/suggestions etc. Would be appreciated. Thank you in advance.
