Front brakes

I'm contemplating a refurb of both front calipers as I need to change the hoses anyway. Will do pistons and all seals as well as the bike is now 15 years old. I've watched a youtube video (don't laugh) which talks about using fine
wet and dry on the pistons if they have signs of corrosion on the exposed parts. Is that for real ?

Do I really need a piston removal tool ?

Also, I've seen a few comments about not being able to bleed the front calipers
easily following a refurb. Any tips or techniques or pitfalls to avoid much appreciated.

Thanks Simon

Hi Simon,

Throw them in the bin and replace with something less maintenance "heavy"

Something like R1 radial that loads of us have done ;-)

i have done loads of these calipers. and i haven't had any issues on bleeding. and i dont use a piston tool either. i use to remove the pads. and put a thin board in between where the disc runs. and then i push the brakeleaver and forces the pistons out so they push on the board, but not so much that they pos out. then i can wiggle them out with my fingers.
i use some special grease for the seals. loctite 8104.

if there are "light surface" corrosion i use some very very very light wet sandpaper. grid 4000 or like that. so im sure not to take anything else then the corrosion.

scotch brite will clean them up fine...

I use compressed air to remove the pistons, plug the other holes with my fingers and the pop right out...

Purchased a piston removal tool which made that part of the job really easy. Tried Motul brake cleaner and brake fluid to try and clean them up but ended up using Wonder Wheels alloy cleaner which was the only thing that did the job. However you must be careful not to leave this on the un-anodized areas or it will damage the alloy. I also bought some red rubber grease to protect and lubricate the new seals. Caliper reassembly starting next week.
