Rant: a guy at the Phoenix shop told me brake cleaner is all the same, then I watched him eat his words on a 2019 F-150
I watched a guy soak a caliper bracket in the dollar store stuff for 20 minutes and the rust didn't budge, but the $9 can from NAPA cut through it in 30 seconds, so what cheaper cleaners actually work for you all when you're doing brakes on rust belt trucks?
