break-in period for brakes?

[plumbcut]

I just redid all the brakes on my truck (77 K25).. with discs all around, I had all 4 rotors turned, replaced the master cylinder & vacuum booster, and cleaned up all the pads & calipers which are fairly new already... braking performance isnt what it was before...

the master cylinder I put on was a new raybestos unit.. the two MC's i had on the truck previously were rebuilt (at least the second one was, for sure) GM's... It had very very sensitive brakes and I liked it .. now it seems like it just a regular old half ton with old brakes.. its a struggle to make it lock up or stop quickly.. i re-bled the entire system. Is there a break in time for rotors & pads? Will performance come back w/ time?

Anybody completely removed that factory prop. valve from their trucks? Its new too and Im thinking it aint doing me any favors with the 4 wheel discs that the truck has. Its REALLY hard to bleed the rear...


If I were to eliminate it, whats the best way to continue the hydraulic lines through that junction?

just looking for some ideas... thanks
