Important

When changing from D.O.T. 3 to D.O.T. 5 fluid or when flushing the brake system, it is important that D.O.T. 3 fluid be removed completely. Old fluid could be contaminated with water and if mixed with the new D.O.T. 5 fluid, it would detract from its effectiveness. The old fluid could a Iso cause varnish deposits if the system is operated above the boiling point of D.O.T. 3. Caution should be used when bleeding because any brake fluid on the pad will contaminate the pad material and reduce brake effectiveness. The fluid absorbed by the pads cannot be removed satisfactorily with any solvent nor by operating the brakes.

Free play of rear brake plunger (4/4A, Figure 2-68) should be approximately 1/16 in. to be sure rear brake cylinder hydraulic pressure is relieved. Adjustment should be made starting with linkage excessively loose, then working toward tightening direction until the 1/16 in. free play is attained.

Front brake lever should have free play up to 1 /4 in. measured at end of lever. After adjusting free play, check for pressure relief indication by removing master cylinder fill plug and watching for fluid bubble when pedal or lever is activated.
