Does anyone know the brake bleeding sequence for a 2007 ram 1500? I have bled the system starting from the furthest point to the closest point to the master cylinder. i still don't have a pedal. and im getting a hissing sound coming from the brake booster. any suggestions?

 

The sequence is rr, lr, rf, lf but getting this out of order won't result in hissing. Brakes are boosted by vacuum and sounds like a hose could be loose. Check all vacuum lines to be snug. Is your truck idling normally? Also, when bleeding brakes make sure that you never get anywhere close to an empty brake fluid reservoir. Air in the system is a killer that you will need a brake specialist to fix.

 

i had no problems before i changed my front calipers. i had vibrations but I found out that was just a loose wheel spacer. i couldnt get my RF caliper to open completely to go over my new pads. so i replaced both for good measure. I've bled the system 4 times now and still no change. Could it be the check valve on the booster?
