Negative Positive
Title: Work but issues with seat shape, strength
Review: I have used Russell Speed bleeders on several cars. They are an okay compromise if you must bleed brakes yourself and / or don't have a pressurized / vacuum bleeding tool and / or need the convenience for frequent track-side bleeds as I do. The internal check valve does work as promised but several of mine have leaked after many bleeding cycles, so I consider this an eventual wear item. The main reason for my single star rating is that they are more fragile than stock bleeders. There are no directions so during a recent install I torqued them to the factory original specs per my service manual, only to have one snap off, thus ruining my caliper and causing a very expensive repair. Another negative is that the seat angles are not identical to stock, so once installed they gall the seat in such a way that you may not be able to reinstall a stock bleed screw without leaking. In the end I'm no longer using them on current or future cars.
Is the review positive or negative?
