Manual saids to use compress air to blow out the piston but what if you don't have access to compress air? Is there another way remove the piston with using compress air?

 

Push the brake pedal down slowly.

 

wouldn't that result in an explosion of brake fluid? I'm talking about when the caliper is removed from the brake system and is on my desk.

 

bike pump will probably be good enough as ling as u can get a good air tight seal

 

open bleed valve and pull it out with a pair of pliers or something. I did it by hand, it was tough, but came out.

 

FIRST OFF; This can be done safely, but you have to be careful!!!

Get a length of 2x4 wood that you can position in the middle of the caliper (where the rotor would go) with the pads removed. Use a piece of rubber with a hole in it that can be used as a seal. Then go to any gas station and use their air line to pressurize the caliper and blow out the piston.

And the correct wording for this is "blowing" out the piston! It will come out suddenly and if the 2x4 isn't there, it could jump clear out of the caliper assembly. If your fingers are in the way, they will be crushed.

You only have to do this once to see why I'm giving all the cautions. Just be throughtfull and carefull.

I'm glad somebody told these guys how to properly do it..

All these ideas will work, just pick one & do it. If the brake hose is still connected, pumping the pedal is probably easiest. YES it'll spill brake fluid all over, but all you have to do is catch it in a pan... Just be careful, if you have any other calipers off, they'll push their pistons out, too.

 

Although using the brake pedal would work, it just dawned on me that you could only do one caliper! At that point, all the fluid would just come out the caliper that has it's piston already removed.

As for not having access to an air compressor, just about any gas station has one for adding air to the tires. However some gas stations may not want you doing it due to their being conserned that you could hurt your self.

Just find one of the stations that have one of the pumps that need quarters and do it before they know what you are doing.

I suppose you could finish the caliper before dismantling the next one. I really don't remember it being that hard to take the piston out. I probably grabbed it with a pliers or something.

 

plug up the line? I never realize how dangerous it is.

 

i just did this to all my calipers. unbolt the brake line, take a punch that fits the hole and push it out slowly. it works and the pistons came out perfectly.
