I’ve been reading a lot about these LSPV deletes but everyone seems to do it in their disc setups but I’ve got a 91 with drums that won’t even lock in snow or ice. I’ve replaced everything having to do with the rear brakes and have gotten zero change. At this point either my master is the problem or it’s the LSPV and at this point if I can just easily delete it I’d like to but from what I’ve heard is it also control fluid volume to the slave cylinders since since drums use much less fluid volume than disc brakes. Any idea?
