Cause of spongy brakes after new front brake pad installation on 1984 Ford F250?
I recently changed the two front brake pads for the first time and followed everything correctly and was fairly simple job. The brakes were fairly worn down on my truck so I decided it was time. I did not disconnect the brake lines but I did spill some brake fluid out of the master cylinder while compressing the dual pistons on one of the calipers.
I've read that this problem is typical of air bubbles and will proceed with bleeding the brakes, but I don't know how they would have entered the system. Also could this problem be a result of dirty fluid? The fluid is dark brown and hasn't been changed in awhile so I'm going to flush the fluid as I bleed the brakes and see if that helps.
Also the rotors looked good with no grooves, dings but there was some minor discoloration in on one of the rotors, and I tried cleaning but did not go away. But I believe I did not have spongy brakes prior to replacing pads so I dont think the rotors are the cause.
Could there be any other cause then besides air bubbles that I should check or address? Are spongy brakes a safety issue?
Thanks!
The spongy brakes is a result of air in the brake lines, it usually takes 2 people who know how to bleed brakes to do this. It is a safety issue with having air in the brake lines, you may not be able to stop as fast as you normally would. If you are not sure on how to bleed the brakes take it to your mechanic and for a hour worth of labor he can have the brakes bled and the truck ready to go on the road.
