Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Safety Recall - Brakes

They are effectively two pistons in line using one fluid reservoir not as used to be the case with two seperate reservoirs & pistons on some cars.

I guess if the seal fails in one you lose one side & if it leaks the fluid can run out affecting both circuits. I would have thought before that the driver would notice.

If you are really unlucky the seals on both pistons could fail. I also thought in the CX case that the casting was porous so pressure would leak and not drive the brake calipers.

But having driven several P4s and one P6 I found the brakes very poor with a long travel and little feel.

The chances are that if one seal fails they will both fail. A single fail will increase pedal travel dramatically, and if you only had rears working with long travel, you may not have time to react before hitting the scenery.

I've had one total brake failure on a single circuit car, when on first application the pedal went to the floor. It happened on my drive, which is uphill to the road and at less than 5mph. It wasn't pleasant.

Called my dealer ,they have received 8 kits , they have made 3 sold cars in the showroom , other cars will be fixed this week . Normally they should receive more kits next week and call me for my car.

Indeed, I actually complained about long brake travel and high push forces on collection of my Plus Four. Was told that was 'normal'. Well, normal maybe to a Morgan. Hopefully the new master cylinders will fix that, but I doubt it. Anyone had theirs fixed yet?

Every trad mog i have owned has had "normal" pedal travel

Post #749155 on here on 23/07/22 from Ross in Aberdeenshire says he had his fixed and brake appeared to be firmer on the drive home.

Interesting chat with Dan at Krazy Horse today. They have received 4 out of the 30 brake fix kits they need to fix customers cars. His understanding is they are being delivered pro-rata to full number each dealer needs.

Subject drifted to the radiator issue. Latest solution revolves around thermal shock in engine when thermostat opens suddenly as turbo kicks in, with hot coolant aided by exhaust manifold within head, stressing radiator as it hits cooler. The solution is a new complex swirl pot with fresh plumbing to same, to mix hot and cold before rad. At least that's what I understood. The factory are performing this fix and have a large team engaged for quick turnaround.

As if not enough a lower wishbone nut has been found under-spec'd so that's due for replacement as well.

That's what I understood re: radiator Richard.

I’d be looking at how the radiator is mounted…..

Exactly my thoughts all along…
I simply do not buy into the swirl pot idea!
