☹️☹️ Typical...there I was learning to love my 2002 955 speed triple....giving the front calipers a good clean...just soapy water and some brake cleaner... Still all connected to the system, but pads removed and caliper in my hand. Pumped out the pots a little to get rid of any grime. When then pushing the pots back in, there was suddenly a "give". One pot has 99% popped out. Brake fluid everywhere!! So, my questions...as I walk to go and get some new dot4... The pot that came out was pretty much entirely out. I have managed to push it back in, quite easily, nice and square. I of course will bleed the brakes and top up as the system is nearly empty However...is this going to be good enough - the seals or does they need replacing for that pot? The brake fluid splattered my front tyre. Will this come off!? Or is the tyre now no good? Hot soapy water seems to have worked.... Should I bin this off as a quick fix and replace the banjo washers, the caliper seals etc....or the fact it has gone back together is all ok? Do I replace all four sets of seals, or just the one that had the pot pop out? Or...as I'm discussing my front brake...really, I know the answers and there's no shortcuts!? Typical, how can the worlds easiest job turn in to the world's biggest ball-ache!!
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
Thank you red thunder....nice to know I'm in good company , and words of advice.... Nothing appears to be 'leaking'. The pot merely popped out I guess as it was pushed out by me pushing the others in! A valuable lesson!
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.
Thank you all. I am adequately reassured....and had also thought it may be an opportunity to actually do ALL the seals and a caliper deep clean...seeing as I'm inadvertently half way there already! Thanks chaps!!
Ah yes, good point! I think I'll simply order two packs of everything - two calipers up front.... I assume (but will check the Haynes manual) that each caliper splits in to two...?
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
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
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
