Modern Vespa

Looks like both of the front shock absorber brake pumps are leaking.
This has led to the anti roll mechanisim needing to be serviced because the hydraulic fluid has drained out completely
Does anyone know if these suspension brakes can be serviced .Is it possible to change seals or do I have to change the entire assembly.

No rebuild kits are available, have to buy new ones.

Check ebay too...
But, don't over pay for them.

I would try changing the copper seals first on the lines

Thanks for the input. It looks like I just have to bite the bullet on the pumps.
Its going to cost a few hundred to replace.

As there leaking why not remove then and strip them down first to see what the seals are like on most there will be the makers name and size normally in inch size's. I think they may be standard wheel cylinder seals as fitted to car brake cylinders. Unfortunatly i have no spare cylinders and have wondered about this very problem as i had a sticking cylinder on my fuoco. If you could strip one down and take some photo's maybe i could help you . Wheel cylinder seals are easy to get hold of in the UK and can be bought for little money.

exactly, whats the worst that could happen? have to buy a new one.

I would try and rebuild it first.

take it apart cleen it and reassemble

Thank all of you for the knowledge and advice.
Mechanics here prefer to replace rather than repair.

Mainly 80% of the population here live in apartments and most motorcycle carpark lots are in the open air areas. There are a few motorcycle lots with covered shelter but all are open to public.

Its leterally impossible to start and finish any form of rebuild on your own.

And like I daid the shops wont do it for you.

However I am always interested in knowing how something works and sharing information.

I have opened up a few topics and will update on those issues with photos where possible .

they only need a cleaning behind the rubbercap there is a pressure valve thereis dirt between metal and the housing no need to spent that kind off money to replace
