Hi Billy….. if you use a small block of wood and a wooden shim that will fit between the pistons you can actually move each piston individually, So the shim Will go across two pistons that are next to each other and the block will go In between two pistons are opposite this will leave one piston free to move, just repeat the process until you have pumped out all of the pistons individually 👍

You are so right about riders needing to understand and maintain their bikes. May I suggest that the order is spring clip, torx pin, pads, 13mm bolts and remove caliper. That way all parts are supported as you work.
I also have a piston expansion tool. Here in Oz, the winter roads are no problem. For your stuck piston, i would space the free pair, and put a spacer to lock the other free piston as best as possible, then use hydraulic pressure to move the reluctant piston. Brake cleaner may help. Then clean the crud.
Your GS has more room between the caliper and rim than my RS to snake the caliper off!
Over here corrosion has not been an issue on road bikes, also it is a 365 day riding season. Gets a bit hot though...😊

Thanks Billy, much better now with the correct torque figures. You put some excellent videos on your channel. Thanks :)

I always tie a tie-wrap to the caliper to hang it from. Then I can scrub without any worries. I dont want to let that caliper go.

Hi billy you put this up the other day👍👍

You won’t get all pistons moving together, next time either put your pads in or get a small piece of wood then work the lever so pistons are out a bit more then clean and dry then get a tiny paint brush and put a bit of silicon grease on the pistons, push them back in job done

I thought I was having a senior moment when I saw this video posted today, it was like a moment from The Matrix! 😂😂 Billy, will you be doing a video for the rear calliper?

@fly1ngf1sh 4 years ago

Hi Billy,
I think you should have given a warning about the risk of pushing the pistons too far out. Don’t ask me how I know…
Also, another tool someone might need before commencing is a brake piston spreader.

What ended up being wrong with the piston?

@joshdsouza292 3 years ago

Thanks Billy, what kind of torque wrench do you use, are these with 1/2” drivers?

@carmelolongo2988 3 years ago

Hi Billy great video thank you! I would suggest to tight the two bolts after holding hard the brake lever, so pads and caliper is well aligned with disk, agree?? Rgs
