Stuck Piston - SRAM Avid XX Caliper

[Trevz]

Hi Guys

 

I have a SRAM Avid XX Caliper, one of the pistons seem to be stuck and the lever is spongy as if there is no fluid in the system. No fluid has escaped so i don't get why it feels this way.

 

Took it off the bike (Front brakes) and looks like only the one piston moves inward when i gently squeezed on the lever.

 

Is this serviceable?

Bleed the system 1st or check for air in the system.

Throw it in the big black bin. Buy a set of shimano's and pretend the who sram relationship never happened.

 

You can thank me later.

Will that fix the piston that is stuck?

Spongy lever is normally a sign of air trapped in the system. As suggested do a bleed and a proper clean of the system.

I used to have these brakes on my bike and unfortunately, once the pistons get jammed, you have very little options. 

It is a known fault with these brakes and there are very few spares available, if you can find them. Your best bet would be to find an old caliper to replace yours. Contact your LBS, they have a spare caliper or 2 lying around that they would be willing to sell you.

Thanks guys. I'll try clean it up and bleed it. Just want it to operate. I do plan to get a new brake set in the next month or 2 so just need it to work a bit longer before putting it to rest.

 

Never had bad experiences with shimano, even Tektro I've had, they were also quite reliable.

***UPDATE***

 

Brake was cleaned and bled and is now working 

Thanks again Guys!

 

I will replace these brakes all together, but for now need them to continue working and just serving their purpose
