A slipping pedal feel, sluggish disengagement or fluid leaking at the pedal assembly are classic symptoms of tired clutch hydraulics. This category gathers the parts around the clutch on the Volvo 164 with the inline-six B30 and the M400/M410 manual gearboxes, where the hydraulics and their mountings wear over the years.
The group includes the master cylinder, rubber pad, bushings and a screen for the hydraulic fluid, plus nipple, clamp, screw and nut for mounting and bleeding. During a rebuild, a common checkpoint is to go through the pedal joint – worn bushings and a hardened rubber pad cause play and uneven disengagement that is easily mistaken for a fault in the clutch itself. The families cover what you need when the hydraulics and pedal assembly are overhauled in one go.
