Need a brake expert
I've notice over a period of about 3 months my brake pedal startedto feelmushy, in fact ifi pressed on the pedal and held the pressure the pedal goes almost to the floor.
Thinking that air got in the line, i replaced the brake fluid with Super Blue.....still mushy
Only other part to replace is the master cylinder....I've just now replaced the cylinder and again replaced the brake fluid, went for a test drive.....the brake pedal is still mushy.
What else could itbe, nothing is leaking
Thanks for any help

RE: Need a brake expert
For years I used a vacuum bleeder. Lately I have gone to a pressure bleeder and it does a better job. The problem with depressing the brake pedal when bleeding brakes is that you force the master cylinder's piston into an area of the bore that is generally pitted/rusted which then causes a failure down the line. I agree with TECH re: the rear lines and calipers need more attention when bleeding.

RE: Need a brake expert
The procedure i use to bleed my brakes is with the pump typepressure bleeder which i bought from IPD.
I took Tech's suggestion and did the rear brakes again, flushing at least 8 to 10 oz. on each brake. Using clear tubing on the bleed valve i saw no evidence of any air bubbles.
Sooo after this second bleed the mushy pedal remains.
Now during normal stop and go traffic the brakes work fine, however, when ijam on the brakes at 50 or 60 mph theres a delay before they grab, once they grab the stopping power is good, its that delay which should not be there.
Thanks for the input.

RE: Need a brake expert
Thanks, Tech and reg, for your effort helping me solve this brake problem.
After bleeding the complete system 3 times, using almost 3 liters of Ate Super Blue, plus the time and money for the brake fluid and new master cylinder, I'am giving up for now.
I'll tackle this problem at some future date.
