Changing my brake pads tommrow and have a few questions?

Do i need to take the top off the master cylinder reservoir when i push the piston back in on the caliper? Or at any time during replacing my pads?





My brake fluid level is nearly at the max and i plan i replacing front and rear pads, should i take some of the fluid out before i start?|||Yes -- definitely - or you will have fluid coming out the vent hole in the cap OR you will hit resistance when you press the caliper piston(s) in to provide clearance for the new pads.





Purchase a NEW cooking baster, $0.99, ( it must clean and not contaminated with any chemicals), and remove all the fluid you can down to the bottom. Push the piston in and install your pads on the pass rear wheel first. Watch the fluid as you push the other pistons in so it does not overflow.


When finished with all four wheels - top off the master cylinder with new fluid and start with the further est wheel for bleeding. Bleed until the fluid runs clear. Move to the drivers rear and do the same thing. You will have to check the master cyl each time you bleed a caliper so it does not run dry or you will have to start the bleeding all over. When you bleed the last caliper, (driver front) , then top off the master cyl and reinstall your wheels and you%26#039;re good to go.





If you do not plan to bleed the system and it is dirty - then is is just a matter of time before you will have to do it or have it done. Now is a good time to do it all.





Note: Do not touch any brake fluid or parts of the master cylinder that come in contact with the brake fluid - especially with oil or grease on your hands or tools. Those chemicals will ruin the neoprene and rubber parts in the entire brake system.|||yes to both|||No leave the cap on and dont take any fluid out just compress the pistons slowly one full turn then wait a few seconds then do it again until they are all the way in.|||Don%26#039;t take the top off the reservoir unless you want a mess in your engine compartment.|||If you leave the top on, you could crack the sides of the master cylinder reservoir.





Drain some out.


Leave the top off.


Compress the caliper cups all the way in.


Intall new pads.


Top off master cylinder.


Put the top on.|||if it is an abs system you do not want to compress back to the master cylinder, it can damage the system. in this situation i would crack the bleeders and then compress the pistons/wheel cylinders back to the starting position. leave the cap on the master so that you do not damage the paint around it.
