MG MGB GT V8 Factory Originals Technical - Clutch Master Cylinder
I wanted to test drive my v6 mgb today but we couldn't get the clutch to work. We hooked up the HTOB and bled about a bottle of brake fluid through the system but the pedal never got hard. I am thinking its the master cylinder but I thought I would ask the experts first. Any ideas?
|For the factory cars (V8 and 4-cylinder) I always recommend reverse-filling e.g. using a gunsons Eezi-Bleed on very low pressure connected to the slave nipple. Did mine that way and it didn't need bleeding at all. On a factory car you are looking for about 1/2" to 5/8" of travel at the slave piston to confirm there is no air in the system.|
|I've got no movement at the HTOB. We pulled the master cylinder apart and I noticed a real fine grit inside the cylinder. How hard would it be to repair/rebuild the master cylinder?|
|Itís very easy to rebuild the clutch master cylinder. All you need to do is replace the rubber seals. Just be absolutely sure you order the right kit. I just ordered a kit for an unmarked master cylinder and once I scrubbed the master cylinder clean, I discover it did have the markings that indicate a different kit is needed. To make matters worse, I still had to replace the whole thing because the walls of the bore had eroded. So look to make sure the bore is perfectly smooth.|
