I am having the same problem. It stops but way to much pedal. The dealer now wants over $150 to bleed the brakes and this is after they told me all I need is rear pad which was $85 that I did not need to spend because the old ones were good for atleast another 5k-10k miles. Is it a certain way the brake on these trucks should be blead. I started with pr,dr, pf and df.By the way do any of you know what the purpose of the canister on the brake booster next to the master cylinder?
