That $80 brake bleeder kit that almost caused a crash on I-95
Picked up one of those cheap vacuum bleeders off Amazon and used it on a 2017 Civic last Friday. It pulled air in past the threads on the caliper instead of bleeding fluid, so the pedal felt fine in the driveway but went soft halfway down the ramp. Double check those seals or just stick to the two-person method, has anyone else had those kits lie to them like that?
Man that is scary, glad you caught it before something worse happened. Those vacuum bleeders are sneaky like that, the air sneaks in around the bleeder screw threads and it looks like it's pulling fluid fine when really it's just sucking air the whole time. I've had the same thing happen on a buddy's truck and we spent an hour chasing a soft pedal before figuring out the kit was the problem. The little rubber seal on the hose end never sits right on the caliper either, it just wobbles loose. Two person method is annoying but at least you know the fluid coming out is the real deal. Pedal going soft on the ramp is nightmare fuel, good thing you were smart enough to test it before getting on the highway.
