I am trying to correct my 89 Jimmy front brake pull to the right, replaced both frt. calipers today and bled brakes. Now it is pulling worse than ever, also peddle feels softer than before.The vehicle has been lifted 6 inches, would this have any effect on it? this is scary when pulling a trailer. Any suggestions on a fix and bleeding brakes? Is there any other place I should be bleeding brake system other than 4 bleeders at wheels? Would shimming left caliper help situation? Keith.
