Doing the Disco-2-step
I've read a lot about the annoying brake pedal issue, but I don't completely understand it.
1st pump, soft/low pedal
quick 1st pump and fast 2nd back on the brake pedal things feel "normal"
I'm close to doing some brake work so I thought I'd see if I can get rid of this too. I've read several people that do a brake job, and replace the hoses but it doesn't fix the issue. And when we're talking about replacing hoses/lines for this issue, we're just talking about the rubber hose at each wheel, right?
So what else can it be and how do figure out what exactly is causing it?
When the pedal is soft/low.....is just a low pedal or are the brakes not evenly applying brake pressure?
Also, does anyone know what the specs are for whether or not Disco rotors can be turned/machined?
Thanks

A while back I broke the brake booster valve while doing plug wires. It's the plastic valve with the red circle atop the air intake. Has a vacuum hose going to the booster. Tried Mickey Mouse patches then finally spent the $35 to replace it. No more 2 step for my 2002 DII. I also did option B with the 3 amigos so I can't be sure. I just know my brakes are a lot better these days.

Worth looking into. Thanks

People say that about the ABS system, but its not actually true. I replaced my master cylinder and ABS module a couple months ago. I did all of the bleeding the old fashioned way and I've got no issues. The trick is to bleed starting at the master cylinder, then right before the ABS unit, then right after the ABS unit, then bleed at each wheel starting with the closest to the master cylinder and working your way back to the farthest, so front drivers, front passengers, rear drivers, rear passengers. It will take longer, but will work just fine.

Is there any way to test the master cylinder for sure?
As far as the calipers go: I've thought about (carefully) getting all 4 wheels off the ground and applying the brake pedal once to see if there's a caliper or 2 that aren't engaged on the 1st push.
