    Is there anything I can do to improve the brake pedal feel on my 2001 Suburban. It has been like this since new. The pedal is mushy and is not as good as the Silverado. Any reason why?

    You could change out any rubber brake hoses with braided steel lines. That would firm up the pedal some. But, that is just how the brake in these trucks are. Like you said it has been that way since you bought it.

    The wife drives the burb and she started complaining when she drove the truck.:grrrrrr:

    I started reading up online and it looks like it is a very common issue with Suburbans of this model year.

    Things I plan to do.
    1. Bleed first and see if there is any improvement, but I doubt it.
    2. Research on proportioning valve details. Is this something that is adjustable? I would like to increase the rear bias a little since the burb is heavier in the rear compared to trucks with just the beds.
    3. Replace front brake pads with something better.
    4. Replace the front rubber brake hose with SS braided hoses.

    Anything else I can do without breaking the bank? Thanks
