Hello folks,My Yams blue spot brakes are badly in need of a service - at the moment a couple of sponges on each disc would be more effective.
So - I’m going to pop the pistons out and clean them up - have a look at the seals - red rubber grease, fit braided hoses etc.
At first I thought ‘this is going to be easy’ (famous last words )as last year I invested in a piston extraction tool which helped me extract the totally seized pistons in my Kawasakis six pot tokicos.
Great I thought - until I remembered that the Yams blue spot calipers are a single casting and do not split in two like the Tokicos - so I can’t get my piston extraction tool in there and extract the pistons.
The Haynes says put a piece of wood over the pistons on one side of the caliper (to retain the pistons on one side of the caliper so as to pop the other side out and then pop the extracted and cleaned set back in and repeat the process on the other side - which means filling the system back up with fluid so as to pop the other side out - which all seems a royal pain in the backside.
Would it be better just to buy a star shaped blue spot caliper tool - unscrew the blue spots, pop out the right hand side pistons immediately behind the holes previously occupied by the blue spots with a bit of wood - which would then give me access to the pistons on the left hand side with my extractor tool?
Sorry it’s so long winded - and I hope you get my drift. Just fishing for informed opinions.
Are you sure? - surely they screw outwards and come out? I’ll check it out.
Yep - I’ve got the tool you mentioned - i’ll give that a go - godamnit - I was really looking forward to getting my moneys worth out of the snazzy extractor set. . . :doze:
I think they screw inwards, but I’m not sure.Never removed them myself.I’m sure I read it somewhere but can’t remember where so I may be talking utter ******** I seem to remember reading that there is a slight ridge that prevents then from screwing outwards - might be worth having a gander at yours …
I’ll look into it Gurniman - no doubt they deliberately engineered the ridge in which prevents unscrewing the blue spots as an exquisite form of psychological torture.
B0llocks -these b*stards are well seized - gonna buy the blue spot caliper tool and unscrew the spots allowing me to poke out the first set of pots from behind and get the other two out with my brake piston rewind tool. I don’t fancy p1ssing about with airlines and g-clamps + I want to use my rewind tool again!
