1 x 3130. This listing is for a Single Line Brake Master Cylinder Seal Repair Kit as used on early XK120 and all XK140. Girling : KL71410. Jaguar : 2653 (if the 1" bore seals appear too large to rebuild  your cylinder, you have the similar but incorrect Morris Minor master cylinder fitted).

IMPORTANT NOTE : These are not miracle kits and depend upon a very fine seal face, so if the bore shows any corrosion that cannot be polished off, ALWAYS REPLACE THE WHOLE CYLINDER AS A SAFETY CRITICAL MEASURE. ANY ABRASION WILL QUICKLY DESTROY NEW SEALS.

We can supply a complete new replacement unit, with special top nut, so SEE : 3120
