View Full Version : Honda Acty Front wheel cylinders
03-01-2008, 03:58 AM
Hi all, I'm looking for front wheel cylinders (drums all round) for my Acty but seem to be having trouble finding them.
Is there an Acty specialist or Honda person I can contact to get hold of them?
I need 4 front cylinders (2 on each drum) if anybody has them.
Cheers 4 now

a wheel cylinder is VERY BASIC... most of the time they get gummed up on the inside and it causes them to stick... if you take the wheel cylinder out, pull the dust boots off of the outside and then pull the plunger out... there is nothing but a light spring on the inside so dont be afraid... do this for both sides and then clean it w/ some carb cleaner and a fine scotch brite pad... just be careful of the o rings on the inside, they are really the only important part... if the o rings are damaged, look for some new o rings at a hydraulic or bearing supply store...
after everything is clean, spray it off w/ some brake cleaner so there is no residue and when you reassemble use brake fluid as a lubricant... i have "rebuilt" several of wheel cylinders this away and have never had any issues... if you dont feel confident in taking your wheel cylinders apart buy one for an 85 caprice that costs like $10 and they are built EXACTLY the same... take it apart, so you feel confident in what you are doing and get that thing stopping again!!!
this method will work on any wheel cylinder... obviously new parts make it easy, but a lot of repairs we have to improvise on... and generally for a fraction of the price... hope this helps...

Thanks for that, the thing is, the cylinder piston is fine, it's the bleed nipple that are the problem (broken off inside the cylinder, dont think they've been out since 1982). I've tried drilling them out and using various removal method but with no luck, hence looking for some new ones.

there are some "universal" bleeders that i have used... they have the flare built into the new screw, its a two piece design, so you would simply drill and tap for the correct threads and you dont have to worry about it sealing as it will do it in the new bleeder screw...

Well, after a full day on Saturday picking away at the rest of the bleed nipple still stuck in the cylinder's, I finally got them out. Must have spend about 8 hours in total doing that! Commitment or what? Anyway, just thought i'd let you know.
