Problems with rear drum brake lock up?
• This can have many causes: • Out of round drums. Have them turned or replaced (easy, cheap) • Change shoes • Out of adjustment or self adjusting mechanism not functioning right • Handbrake cable out of adjustment • Proportioning valve out of adjustment or faulty • Incorrect cylinders installed (17mm vs 14 mm, they look very similar but make a 40% in brake pressure!) • Faulty master cylinder. • What grease should I use on the rear axles of my VW. • A high quality Lithium based grease with Molibdenum disulfide (MoS2) (all VW shops have switched to this). In general you can use “Moly-Slip” grease where you used to use the old “White Lithium” grease. MoS2 works a bit like graphite in that it doubles the lubrication properties of the base grease. Note: Generally do not mix greases of different base, e.g., an Aluminum based grease with Lithium base. They may react and lose lubrication properties. Note2: CV Joints use a special grease, less viscous grease.
