Squishy brake pedal

My 2003 Tacoma has a squishy brake pedal even after bleeding and changing the brake fluid. Any thought on the real problem?

 

maybe the pads are too worn? after putting new pads in my car i generally can feel a difference in pedal feel.

worst case scenario you may need a new master cylinder

 

bleed the brakes, look for any leaks, check the rear drum cylinders for leaks too, and then id start looking at the master.

 

Bleeding the brake fluid is not quite the same as flushing the brake fluid.

Start at the pax side rear and bleed / flush until you have a steady & clear stream of new fluid coming out. Do not let the master cylinder run empty. Then move to the driver side rear brake and repeat. Then move to the pax side front brake and repeat. Finally and lastly move to the driver side front brake. Pretty common sense, but not everyone knows you must bleed / flush from farthest brake to nearest. On a 2003, you may go through 2-3 bottles of brake fluid.

You need to be using a vacuum pump and brake bleeder kit and any evidence of air bubbles coming out of the bleeder screw(s) is proof you have compressible air in your brake lines. Thus, a mushy brake pedal feel.

It might take you 100+ pumps of the brake pedal at each wheel before you bleed / flush all the snot outta your brake lines. The brake fluid should not dribble out, it should pulse / squirt out when your lines are clean and clear. And again, you must keep your master cylinder full at all times.

It helps to have a friend in the driver's seat while you do your thing outside.

During this entire procedure, you need to be looking for leaks. Front calipers and rear drums need a close visual inspection.

Last but not least, your brake lines - the rubberized end pieces - on a 2003 may be soft and completely elastic by now. Soft & worn out brake line ends are often a very common source of a soft pedal feel.

And, again, when you are doing this, be looking for leaks everywhere.

If you do this correctly, and for typically less than $100, you should easily be able to make your brake pedal feel like a brick.
