Can i mix mineral oil?
Im doing it top down and using halfords bike specific mineral oil but i will have to mix the oil.
Will this be ok or should i bleed the old oil out completely.
I can't do it bottom up.
It'll be fine.
Why can't you do it bottom up?
I usually run it through until it has all been swapped and the colour is close to the new stuff anyway as new fluid is cheap and better.
i have mixed them in the past no problems
why can't you bleed it from the calliper?
can't do it bottom up because i don't have a syringe.
can't do it bottom up because i don't have a syringe.
fair enough, i personally find i get a better bleed doing it bottom up. You can get syringes from ebay, couple of quid for 5 decent sized ones
i had one and lost it like a muppet. I did it bottom up last time and it went really well.
At this rate im tempted to just let the LBS do it.
I might leave it till the weekend and pop to JE James and see if they have a spare one.
Oh and i don't have the damn brake block either. it's going really well so far.
I got syringe from local chemist for 50p
Use a piece of wood as the brake block. Bleeding top down is fine, just a bit more of a faff.
Do it
what stue said, local chemist. dirt ceap and exactly the same as stuff you get elsewhere.
tried chemist they didn't have any. Je James gave me one free last time. i'll try the piece of wood cheers.
