ok the suburban needs new brake pads this weekend but i think i'll replace my calipers too. not sure though. they're the origninal calipers (160k miles on em) and the truck pulls HARD to the left when i have to stop fast. like changing lanes kinda hard. it's really starting to bug/scare me. so would it be wise to replace the calipers too? could they be causing this? it needs an alignment but would that cause this pulling? and my electrical problem... i blow the backup and turn signal light fuse about once a weekk. why is this? its a 10 amp could i just put a 15 or 20 in it?
