If you only brake while going straight theoretically your brakes should wear evenly but that never happens. Most people make more right turns than left (here in the states) turning into parking lots, driveways etc. so the wheels turning at different speeds = different friction heat so one side will wear faster. add into it the fact that the brake pad is not rigidly fixed to caliper piston and you can add in rubbing from centrifugal force and a host of other uneven outside factors. If you ever come up with a way to keep the wear even I'd love to hear how. For now all I can do keep checking and change them in sets when one gets bad
So just so I understand, if you take two metal brake lines of the same diameter but different lengths and fill with brake fluid(non-compressable) then apply the same force/pressure to both lines you'll have less pressure on the output of the longer line? I don't think that's how hydraulics work unless you have air in the system. I was wrong once before though. I can see rubber expanding but metal not so much.
Besides, if pressure was actually different with different length lines would the car not pull hard to the left every time you braked in pretty much any lhd car?
Just asking as there is a lot of stuff posted here that is wrong and followed as gospel by people who just like to argue for no reason.
