Soft break pedal?

in the last few days, I have noticed that I have to push my break pedal in alot further to stop the car, I just changed the break pads a few months ago, and topped off the break fluid at the same time.


Am I just low on break fluid? I feel like the next time I put the breaks on, the pedal will hit the floor and nothing will happen.

I don't know if this just happened all at once, or if it gradualy got worse. I just noticed it last night, "gee, I sure do have to push the break pedal in pretty far".


Thanks for any info!

hey error 404, you could have some air in the lines that or the pads are worn alot. Have you look at the pads, checked the fluid recently? if the pads are good then try bleeding the system that should help, let us know

I just replaced the pads a few months ago. and topped off the fluid level.

How do you bleed the breaks?

Get a small bottle like a water bottle. Fill it with some brake fluid. Get some tubing to put on the bleeder valve and come down into the bottle below the brake fluid surface. Loosen the bleeder valve to the point it isn't open but easy to open and close. Have someone in the car pump the brakes a few time to build pressure. On say the fourth pump have them hold the pedal down. While the pedal is down open the valve. Look in the bottle to see if any bubbles come out. Should look like if you were to blow into a straw in a drink. Close the valve after a couple seconds and have the person in the car pump the brakes again. Repeat the process until no bubbles come out of the end of the tubing in the brake fluid.

And don't forget to check the fluid resevoir between bleedings to make sure you don't run out of fluid.

Also, you may want to replace your rubber brake hoses with braided steel ones. Sometimes the old hoses will bulge under brake pressure and cause that spongy feeling.
