Master brake cylinder is apparently bad, though it still stops the
car.? But lately, when braking, there's some bumping sounds at each tire
revolution as car slows down, and those bumps can be felt in pedal and
steering wheel.<br id="yui_3_16_0_ym19_1_1506741192438_40800"></div><div dir="ltr" id="yui_3_16_0_ym19_1_1506741192438_40801">>
