I just replaced all four brakes on the the Disco II. You really can't tell when pressing the brake pedal. The truck does stop better. Should the brake pedal become more sensative when putting on new brakes? Kind of like stiffer? Do you guys think I might have to bleed the system and if so do I have to do each caliper or is there one that can bleed the whole system? |

What timing. I have just changed my breaks on my 97 D1. My break peddle was very mushy. I had to bleed the one wheel I knew I had a problem with. See this was my first time changing the breaks on my disco. I did not realize you can change them without taking anything off. My bad. So I took apart the right front and leaked braking fluid everywhere. Once it was together again I bleed that one wheel and everything is fine. If you took apart all four I would bleed all four at once. |

If you just push the calipers back in when you replace the pads, you force old, dirty, nasty brake fluid back up to the reservoir and ABS unit - NOT a good thing. Hydraulic components really do _not_ like contaminated fluid.
Next time, crack open the bleed screw at the caliper when you retraact the piston. Then bleed the brakes.
I suggest that you thoroughly bleed your brakes ASAP until you see clean fluid from each bleed screw. This should be done at least every couple of years, since brake fluid is hygroscopic (absorbs moisure).
And no, hydraulic brakes are totally self-adjusting, as long as they are working correctly. The pedal feel should remain the same unless there is a problem like air in the system. |

When you change brake pads the pedal feel should not change. If you used the same pads as before the stopping performance should be the same after a short break-in.
Changing fluid should not affect performance either, but pressure bleeding an ABS equipped vehicle often results is a firmer pedal due to removal of air in the ABS body |
