Hello

I took pistons out by compressed air. I have a small air compressor and I fitted a air hose pipe of the compressor to the brake fluid connection hole. It was necessary to "seal" the connection to push rags around the "fitting".

Lock one of the pistons in caliber with some kind of pressing tool. Other piston jumps out. Then clean the piston and replace seals. Then push it back in the caliber and lock it with pressing tool. Now it is others piston's turn to jump out.

I'am from finland and english is not my morher tongue, so I hope you despite all understood what I tried to say.

Best luck

Kai

Not sure what you mean by OUT, but you can use the brake to make them come out, or you can you a U clamp to squeese them in. Make sure that you remove the calliper first.

ARE YOU GETTING GOOD PRESSURE FROM YOUR MASTER CYLINDER IF NOT CHANGE THE SEALS, ARE THE PISTONS SEIZED IN THE CALLIPER IF SO FREE THEM OFF. WHEN YOU BLED THE SYSTEM DID YOU BLEED IT BY PRESSING THE FOOT LEVER OR BACK BLEED IT? I WOULD TRY TO BACK BLEED IT WITH A LARGE SYRINGE AND HOSE ON THE BLEED NIPPLE WITH BRAKE FLUID AND WATCH FOR AIR IN THE FLUID BOWL. GOOD LUCK

How to Replace front fork seals on Suzuki GSXR 1100 K model


Remove front wheel, brake calliper etc . Undo top and bottom yoke pinch bolts and slide out fork leg. Clamp chrome tube in a soft jawed vice and remove top nut carefully as it is under some load and will fly away, (but its not too much you can hold it with your hand). Tip out remaining oil slowly so as to not loose spacer on top of main fork spring. Clamp lower aluminium leg in vice by calliper mounts and remove allen screw in extreme end (if the wheel spindle was in you couldnt see it) This is the only part that might be a problem as the inner end may turn. An impact wrench may help or if not a simple broom handle shoved up the other end is often enough. Once this bolt is removed the leg will split. Now lever out the dust cover to reveal the wire circlip holding in the fork seal. Remove the clip and lever out carefully the old fork seal. Fit new seal using a large socket and mallet or something similar and reassemble in reverse order, not forgetting to add correct amount of new fork oil.

1998 Suzuki GSX600F, i recently got knocked off my bike and i have had to strip the callipers and clean them out as the brake was unbelivable spongy. i have put then back on and bleeded the brakes as...


Are you sure the discs or calipers wernt damaged or bent in the accident.
You dont normally need to strip them to bleed air.
If the seals are not leaking, probably wont help to replace them

Wheel cylinders for honda motorcycle froze up. How can I get them apart.


Assuming you mean to get the pistons out of the calipers, what ever you do, do not try to free them with a releasing oil. It will make the seals swell and the problem worse.
Try fitting a grease nipple in the bleed screw hole and pump them out. Makes a mess but is the safe way. Alternatively, you can use compressed air but wrap the calliper up in cloth before applying it. When the piston comes loose it will fly like it was shot out of a cannon and can easily take the tip of a finger off, or worse!
You will probably find that there is corrosion of the aluminium caliper behind the dust seal, causing the seal to bind on the piston. This must be totally cleaned out. Use some rubber grease (available from auto stores) in the groove before fitting the new seal to prevent it happening again.

Brake pad replacement


you should not need any special screws, a spanner or socket to remove the brake calliper. Then a large flat screwdriver, to prize open the gap between the old pads, as they are worn down and you will need to do this so the new ones fit in. The only one precaution to remember, is never suqeeze the front brake lever while you have the caliper off the bike, this could cause the caliper piston to fall right out. After you replace the pads, and put the calliper back on the bike, you will need to pump the brake lever a few times before the brakes feel right. you should not have to bleed the brakes after that job

Calipers are hung up


This usually happens after a long period of storage: the first time you apply the brakes, they fail to release their grip on the brake rotors. Moisture in the system causes corrosion to develop which prevents the caliper pistons from retracting when the brake lever (or brake pedal) is released.

What you need to do is take the calipers apart and remove the pistons. With the pistons removed, carefully pry out the rubber piston seals and soak everything in soapy water. Using a dental instrument or similar device, be sure to clean all of the corrosion from the groove where the piston seal fits into the caliper. Replace the seal and reassemble everything using clean DOT3 brake fluid as it goes back together.

Refill the system with new brake fluid and bleed out the air. Once completed, your brakes should work like new.

Front brakes binding


if pistons can be manually pushed back, then you may have **** in the brake line going to that caliper. a blockage will cause that. the piston seals may be damaged. they are square so when the piston goes out, the seal rocks forward but wants to pull the piston back when pressure is released.don't pull the caliper apart unless you know what your doing. and if you do then i don't need to explain the process.
