Motorcycle Brake & Rotor Replacement : Replace Motorcycle Brake Pads

[jordanherrmann]

Ah man, I pulled the brake. Then hammered out the pistons with a nail to get the wheel back on. And now there is no pressure when I pull unless I pump the break really fast, but even then It's only slight pressure that fades away. And I took all the fluid out of the break to replace it. Any advice? I can't afford to take it in or get new brakes.

thanks man you the only one that point out the problem with closed in pistons.I been down for 2 days because i could not findout how to open the pistons.

Clean up the ends of the pistons and smear with red rubber grease, to help against any future corrosion or siezure.

I gently use a 'G' clamp to push the pistons in, one at a time, you then get a feel if they are sticking or seized.

And i lightly smear copper grease over the back of the pads to stop squealing.

Make sure none of the grease touches the pad surface or discs.

But clean the discs afterwards with a rag and brake cleaner just in case.

Nice advice at the end, i pushed the rear brake pedal when doing this and luckily i still managed to open it otherwise i would have been there for ages like u said trying to open it

yeah I wouldn't try move them when new pads are in... also I didn't see anything on using grease and copper grease...

One mistake here!

Spread the old Pads, not the new ones.

I recommend spreading the pistons with a tool when your old Pads are still in, so that the pistons are as far back as possible.

I would not recommend prying the new pads!!! as you might damage or score the braking compound.

One the pistons are back you can replace with new pads and you wont have to risk damaging them!

this video is actually not bad

2-piston brakes are easier to change than 4-piston

When you open up the pistons before inserting the new pads, do you have to remove the top of the master cylinder first or can you do it without removing it?

@ 12monkeys They retract a bit whenever you let off the of breaks, otherwise your vehicle, whether it be automobile of motorcycle, would stop moving all together. It's because you have more material being put in than the original that you have to spread them. If you have 1 inch of material originally and you are putting two inches in, you'll need to open it up to allow the same room for the rotor to fit into the same spot.

in the end of the video, it says pressing the brake in, will need to push pistons/pads apart to get them back where they started... Why wouldnt they retract by itself when you let go of the brake anyway?

Excellent video. Can I ask what the tool was that you used to imitate spreading the pistons? Where can I buy one and what is it supposed to be used for?
