While you are in the area, you would be wise to check the brake pads and the power brake assist function.

1. During the tour I had of AP brakes, they wanted me to try their newer calipers we discovered that the pads given to the MMC and our community, don't fit. They leave a lip which cpould have an unknown effect. Simply chamfer it off. https://www.gomog.com/allmorgan/brakehistory.html#WATCHPOINT:

2. The power brake assist harnesses the engine-created vacuum to assist in braking. I was reluctant to try it at first, but the good Mr. M. Baldwin convinced me over a pint. He was right, it is fine brake "assist" rather than power brakes (that IMHO, robs the foot [and the driver attached to it] of any brake "feel". Over time, something can malfunction with the system, For example, the underside of the vacuum hose to the engine, can become flaccid while the visible side looks great. In effect, the flaccid side acts as a valve and refuses to release the vacuum, locking the brakes on.Or the inner bellows can act the same. Should be easy to test..when your brakes lock, detach the vacuum hose at the engine.

I never wrote up the tour as I too think the Mulberry Hispecs are a better buy. But these Caparo thingies were given to me and they work fine
