Brake upgrade.
Trying to improve on the standard crummy brakes that are on my 03 Silveradowith the 5.3. Nothing wrong mechanically, just they have been garbage from the day it was new. Brake pedal spongieness has got to go.
Been told that I can upgrade to a newer model Vacumm system and DON'T really want to go with the Hydralic set up at this time.
The local recycler is asking me a few questions I can't answer.
Off an 05 Silverado he is asking me the RPO codes.
Vaccum JC4, JF3, or JF7.
Anyone know which one is the better of the bunch???
Which 1 would be a direct fit replacement???
Thanks
