brake isssues

I've tried searching the site but I can't find exactly what I'm looking for. So hopefully someone could help. I have a 2010 DC 4x4 6 cylinder Tacoma that I just changed the front pads and rotors on. At times while braking I need to pump the pedal a couple of times in order for the brakes to work. No all the time. It almost seems like there is air in the brake lines but the bleeder valve was not opened during the installation. I've replaced the pads before and never really had any issue. What do you guys think?

 

X2. Always bleed the lines when does ng brakes. And change/flush fluid every 2 years for optimal performance.

 

yeah bleed the system.

Also when changing pads. NEVER push the fluid from the calipers back into the system. Depress the brake pedal and lock it in place (via a brick, zip tie, another person.) This makes it to where fluid cant be pushed back up the line. Crack the bleeder screw, and then push the old pad in to push out all the nasty crap in the caliper out. Replace pads, put caliper back on. then pump the pedal to get brakes back before moving.

 

^^^ This exactly. This is one of the biggest things people forget about. Not flushing the fluid will eventually lead to caliper failure from corrosion and the breakIng ability will decrease greatly.

 

Thanks for quick reply. That make sense, I have never flushed the system, how about the rear brakes, would you think they need to be adjusted to accommodate the new pads and rotors?

 

Be careful not to let the reservoir go dry while you're flushing the system.

 

Please forgive my ignorance, but are we bleeding the front 2 brakes or flushing the system and removing the all the fluid and replacing?

 

You'll want to flush the entire system. Replacing all the old fluid is the goal.

 

As a side note, once the system is bled and you're confident there is no air in the line, if you still experience squishy brakes there is another problem. Master cylinder worn out, caliper pistons leaking, things of that nature.

TTT for so many TW members complaining about brakes and never heard of flushing your brake fluid on a regular basis.
