Classic Mini Brake Proportion Valve MK III Except Cooper S

Classic Mini Brake Proportion Valve MK III Except Cooper S
Part No: 21A2031
$200.95
Qty:
Fits the following:
Classic Mini
For all MK III minis to 1978 except Cooper S MK3 which used 21A1774. Fitted mainly to cars with 3/4" larger bore rear wheel cylinders.

The correct regulator valve for all MK I/II Minis plus all Cooper S inc MK III is 21A1774 where most models had 5/8" bore rear wheel cylinders.

The only difference however is in the poundage of the spring, 37H2009 which is weaker for this version to compensate for the change in wheel cylinder sizes.

See MS72 for adjustable type. The stronger spring in 21A1774 is available as 27H6620.
