Spongey Rear Brake
my rear brake keeps going spongey! Its a basic Shimano (M395) set up that came on the bike. I replaced the pads (front & rear) in May. Front has been fine.
I have bleed the brakes twice since May. Initially it's fine but then gets spongey again. I did have a wee bit of sticky piston in the rear(!), could that be the issue?
Do i take the whole thing apart of just upgrade to SLX?
thinking it through, it must be air getting into the system (ovs!). So i reckon that will be the seal on he piston that was sticking (maybe?). I cant find a maintanence kit for shimano brakes, so it looks like new ones.
bike discount in Germany are doing a set of Deore for £72 + del or SLX for £75 + del,
cheers all for the input.
If it's not happening frequently, you could try a mini-bleed to see if it helps get the air out and firm them up again: http://www.epicbleedsolutions.com/blog/5-minute-shimano-mini-bleed/
Also, most brakes from outside of the UK will come reversed (left = front, right = rear) so you may have to swap hoses.
thanks for the link, not seen that before. I have an epic bleed kit and have been doing the full bleed. I didn't know about the reversed brakes from Europe either. My Dia-Compe's on my BMX in 1983 were right hand rear, etc. My trek has an internal rear cable, so i would be dis-assembling any way and thanks for the advice
Why buy from Germany when UK shops are cheaper? And free delivery, brakes the correct way round etc http://www.merlincycles.com/shimano-deore-m615-disc-brakes-front-rear-set-62194.html?utm_campaign=googlebase-GB&utm_source=googlebase&utm_medium=shopping&utm_term=Disc+Brakes&ucpo=23750&gclid=Cj0KEQjwsb-vBRCLj7TvqpGx_MoBEiQALgFGnjC4bAX6LF9LZ2tw1oE8yMoZCc99G0bOVpPf5ik5ifgaAj6M8P8HAQ
