my brake pedal on my nissan sentra has been getting pretty spongy/soft lately and i feel that it should be bled. but at the same time, its getting close to a brake pad change. After researching a bit, I wanted to try doing both myself. I was wondering which procedure should be done first? or does it not matter?Which comes first: bleed brakes or change brake pads?Hi .... well ... changing the pads should not be that expensive and if they need to be done anyway ... might as well do it for peace-of-mind. I would do the pads first, and then bleed the brake fluid at all four wheels until the fluid runs clear.
if you look around on YouTube you can find a tutorial for these things ... do that first so that you have a better idea of what to do ..... it is fairly easy, but this will make it go much faster for you ...Which comes first: bleed brakes or change brake pads?Do the pad change first then bleed the system.. Tip always bleed your brakes into a jar as you can keep the tube covered with fluid and prevent any air entering your system ~~Which comes first: bleed brakes or change brake pads?the order of the procedures does matter. normally when you change your brake pads, you open the bleeder valve to compress the piston. it allows you to put the pads onto the caliper and over the rotor. now since you opened the bleeder valve, you allowed air to enter the line. once you change all 4 sets of pads, bleed your brakes.Which comes first: bleed brakes or change brake pads?i agree with bobcat. but if you dont have any exp changing brakes try have someone around who does. haynes manuals are a great help too and not just for brakes.Which comes first: bleed brakes or change brake pads?just for the record, since i myself recomend changing brake fluid bianually, i would just use a c-clamp to compress the calipers to put the new pads on, without opening the bleeder, and not having to bleed the system, however if you have a spongy peda;, you need to bleed. btw after 11 yrs of fleet mechanic work, you dont add brake fluid. low fluid is an indicator of a problem not a solution of adding fluid.
