Thread: Series 3 Hydraulic issues

After the 12 years my 3 spent in the yard all the hydraulics were shot, I managed to kit the brake master and repair the slavecyl, I fitted an after market clutch master cyl i picked up from super cheap it has a much bigger bore and with simple mod work slipped in and the clutch pressure after bleeding is that of a true mans clutch, I started on the wheel cyls after dropping the drums and using boiling water to remove the black crud and old fluid we condemned the cylinders, they were easily re kitted with new 1in and 1/4 cups, she really needs new rear linings one has strted to disbond from being fluid soaked, so these were tidied up and the drums refitted, the fronts required the cylinders being kitted the linings are like new, can I successfully hand bleed the old fashioned way I dont have a power bleeder?

You can use some vice grips and the flats of a couple of spanners to clamp the flexible brake hoses. Clamp between the flats of the spanners so you don't tear or crimp the hose. This makes it easier to bleed one section of the brakes at a time.

Clamp both fronts & do the back.
Clamp the back & front (R) to do the left
Clamp the back & front (L) to do the right

after you finish, if they still feel spongy, you can clamp of one section at a time to test and by process of elimination, determine where the air bubble is.
