@john: once I have fixed the leakage, I'll tell you how, just in case...

Hylomar blue?

Well if I was leaking I would not be using Hylomar
John

@John: What type of Hylomar do you use? Your talking about Silicone Sealer, not al Hylomar products contain silicones and will stay sticky.
This one? ; https://www.silmid.com/products/hyl3100 ... silic.aspx

Hi Harold,
I always used "Blue Hylomar" I don't think you need the high temp red one, blue was recommended by Brit Leyland back in the day to stop leaks between alluminium and cast iron with different expansion rates, it stays elastic and flexible
John

OK, thanks, will try that!
It now has to seal between the steel cover and synthetic seal, hope that will work.

Cheers Harold

Good luck

Both sides of the gasket too? de-grease the surface on the steel parts?
Normally I put engineoil between gasket and surface...

Degrease the back plate and pressed cover and put a light smear of sealer both sides of the gasket 'inshala' it wont leak again
john

its the engine oil squeezing out between the cover and plate causing the leak
john

No it's not...
The drips come from the oilseal...

A few weeks ago I tried to cure the oil-seal-leakage as mentioned before.
When I was finished I wanted to take it for a spin, but the piston in my left front caliper did not move anymore. I took the caliper off and tried to remove the pistons. One was no problem, the other one did not want to move. I bought a new front caliper, fitted it and bleeded that brake.
After that I drove it around, but it brakes late, sometimes just before the pedal is at it lowest point or sometimes have to pump to get pressure.
The master cilinder contains enough fluid, maybe there still is some air in the system.
Can air be in the caliper somewhere and stays in when you bleed it?
Will bleed it again soon.

I drove it around for about an hour (with poor brakes) and than put it in my garage.
The good thing is that no engineoil dripped under it since, I hope the leakage is cured!!

Cheers Harold

Great that you sorted the oil leak

Does sound like you still have some air in the brakes. Air can hide in weird places but maybe after driving it for a bit it will have worked its way to somewhere it can be bled from. After years of messing around with traditional bleeding methods I recently got a Gunsons eezibleed, the one that uses the pressure from a tyre to push the fluid through. I've had no problems bleeding with that and it makes it SO easy.

@Sanzomat: What a coincedence, I bought exactly that set last week
Hopefully I will have time to try it out next weekend.
What tirepressure did you use?

Cheers
Harold

I bought a Gunsons eezibleed kit last year as well & it worked really well.
I got air in the Libra's system (some how!) when changing the rear discs & pads. It sorted that out no problem.
I don't think tyre pressure is too critical - so long as its pressurised. I just put it on the spare with about 20-22 psi in.

I've used eezibleed for some time, it works I did have to make funny master cylinder covers to fit bikes but still works
