Re: Why am I having to double pump my brakes ?
Having to pump the brakes is related to one of two things. Air in the system, or brakes out of adjustment.
Fixing the air is getting them bled properly.
The adjustment is usually the rear shoes having too much slack. If your E brake actuates the rear shoes,
(mine doesn't SJ410...) try pulling the E brake up part way. Does it get better? Its the rear then.
If its not the rear, loose front wheel berings, or rotors with too much side to side runnout can cause the
calipers to open up, requireing the double pump to close.
Pet peeve guys and gals. If nothing else is up to snuff on your rig, make sure the brakes are. Its your life
were talking about, and possibly others... Possibly your loved ones.
