Help! It's A Disaster!!

As long as it all went back together without having to force anything and it was all clean, reassemble everything and bleed the brakes until you have new fluid through the system and go do a short test ride to check and job done.

Make sure you have all the brake fluid cleaned off the tyre & paintwork, the soapy water is fine.

 

Did this myself few years back
As you have said, top up the fluid, bleed the caliper and also at the lever/master cylinder if needed

Keep it clean and watch for further leakage
So long as the oil didn't get on the pads these will be fine
So long as you cleaned the fluid off the tyre and any paint work thoroughly then there should be no damage
Only if a pot sticks causing a pad to rub against the disc causing increased wear would you need to change the oil and dust seals in the caliper
If you change one set of seals, then do them all and replace all the fluid in the system

 

A blessing in disguise......brake fluid is water soluble which is why it takes up atmospheric water.

A good clean all round and dry off with kitchen towel. Personally on a bike that age I would replace the seals and lightly polish the bores and pistons with Brasso before the big clean and new fluid/bleed. Good as new....especially if SWMBO doesn’t see the callipers in the dishwasher.....

The piston popped through hydraulic pressure just as if you HAD pulled the lever.

 

I am trying to mend my ways because DD gets hydrophobic.

 

You will need to replace/anneal the banjo washers

 

I looked up hydrophobic, read as much information on the internet regarding said subject.

I still have no clue what it means,all I know is, change the brake fluid every few years

 

What Oldyam said.

 

Noooooooo I can’t deal with intelligent answers anymore . I only ever have to answer to MD,s Councellors and suchlike
Just ask me which is faster over 400 metres
Usain Bolt
Glyn Phillips riding a Ducati Desmodesici....
Plus if you give me an empty glass I’ll throw a wobbler..... that happens if it’s full too
WHAT DO I DO NOW

 

If you remove the banjo washers and heat with a blow lamp until red then leave too cool on their own in air. Do not cool in water
They’ll be as good as new, in reality it takes about ten minutes

 

There can be a positive to that, carry out the work at someone’s place who you dislike

 

I’ve only ever used m10 so I guess so,but heat in a pan if you’re worried about a blowlamp as long as they go red and cool naturally they become soft again and like brand new.
Because I’m tight I’ve done this at least twice before replacements were bought
