Ian, we are allowed to go for a drive provided any passengers are from your household and if you get out of the car, to keep the statutory distance apart.
I now take my dogs a couple of miles in the Land Rover to a walk in the country where if I meet anyone it's easy to keep the statutory distance. Walking them from home means pavements where it's impossible to keep the distance unless I walk in the road.
I know this is nothing to do with leaky wheel cylinders but it's easier to post it here than start another subject.

Hi Vic,
good to hear from you and to hear you are fit and well!
As far as we can tell, you are technically correct, but there are many reports of folk being interrogated during car journeys, and also being forcibly turned away from many locations.
We are most familiar with the situation in Scotland and the North of England, and I know there is quite a bit of animosity towards folk who travel to the usual recreational areas. I guess a short drive to somewhere local is the most acceptable to everyone?

We are both getting on a bit (like many MG owners I suspect) so we do fall into the category advised to stay at home, so that's what we are doing. Thankfully we have a garden and a garage with two MGs, and a well stocked cellar, so we should cope!

Stay safe!

Mario, when you do the brakes , do one at a time this let’s you see how the other side is done, one point to look out for is the leading edge on the brake shoes, these should be going with the rotation of the wheel.

There are you tube articles on this, I have seen then in the wrong way before

Thanks Jim. This is making the assumption that both sides are correctly assembled of course!

Like you, I have seen several incorrect assemblies - shoes and springs incorrectly put together.

The leading edge of the brake shoe is the end where the lining doesn't go to the end of the metal .

[attachment=0]20200409_183449.jpg[/attachment]Hi all,
really hope you are well and safe.
At last the parts ordered from MGOC arrived. This time they took a while to arrive and also kept the parcel quarantined for 4 days.
Any way i need your help as i am confused (please bear with me my ignorance).
I recieved the complete wheel cylinder and also a bleeding * as per attached photo. Th is extra as the bleeding * is already attached to the wheel cylinder. Also can you advise me the small sort black plastic nipple is.
thanks in advance
mario

Hi Mario, good to hear you are well.

It looks like you have been supplied with an extra bleed nipple. This often happens when you have ordered all the parts you need and then find that some are already included with the main component.
The small black roll pin fits into a hole in the brake back plate, provides location only. The cylinder is held in place by a "C" clip on the outside of the back plate. Can be difficult to fit.

Can be difficult to get the air out of the system due to the location of the bleed nipple, but can be done!

The C clip can be made less formidable if a gradual approach is taken:

- Locate one of the 'ears' on the side of the cylinder (not in the groove)
- Keeping a thumb on the first ear, lever the 2nd ear into the same position using a screwdriver, copper grease and eye protection (in case it pings off)
- Snap one side into the groove by using the screwdriver as a drift and hitting it smartly with a hammer
- Repeat for the other side.

If you put the first ear into the groove straightaway then the task becomes a lot more difficult.

I think there is an inexpensive tool for replacing the C clip.
