Not a good thing. Is there a pedal arm stop missing? Is the master cylinder fully returning?

2001 Ford Taurus LX, I bleed the brakes passenger rear to drivers front. I still have a lot of petal before getting much from the brakes?

Bad calipers or master cylinder can pull in air EVERY time you release the pedal if the cups are bad.
OR adjustment can be loose at the drum or disc. Make sure when you bleed it that you keep the master cyl. reservoir topped up so it doesn't get low enough to pull air also. don-ohio .

How do I replace the brake light switch on a 2001 gmc sierra

Follow the brake petal up to the brake rod. Unplug the switch wire then take the clip of the petal then the brake light switch should slide right off.

Had brakes when parked, replaced front rotors, pads, turned rotors, replaced brake lines no rear brakes replaced hubs,shoes wheel cyc, lines master cylinder, booster and bleed.bypassed abs system. could...

Sounds like you have an air lock in your distribution block or it could be a bad distribution block all together. Sometimes you can tap it lightly and the air lock will bleed out. Also check your vacuum booster. If it is real hard to press the brake petal down, with the motor running, the vacuum booster diaphragm is blown, or there is a vacuum leak in the line to the booster. Pull the vacuum line off the booster with the engine running to see if there is vacuum to the booster, this will likely make the engine stall out if the booster is working properly. A little trick I do when bleeding my brakes is take about 16 inches of clear tubing that fits the bleeder, then get a quart Mason jar stick the tubing that is attached to the bleeder into the jar, then add about and inch of brake fluid to the jar and start pumping the petal. Always keep an eye on the jar and your master cylinder as to not let the master cylinder run out, or the jar to overflow. Hope this helps, good luck. If I think of something else I'll do another post.

Why is there clutch fluid dripping inside the cab?

most likely the master clutch cylinder rod seal is leaking through the fire wall where it is bolted to, when appling pressure to the clutch petal, it runs down the clutch rod that is connected to the petal, replace the clutch master cylinder.

No brake pedal

sound's like a booster problem, providing the rod is seeted correctly to the master sylynder,the master is installed correctly and primed and wheel sylynder's are not leeking, double check your work,then i would start back at piont A .unfortunatly the booster may have to come back out. good luck

I think I need to replace my brake booster.

Did you bench bleed the master before you installed it???? Engine off, have someone push the brake petal down and hold it down while you crack the brake line loose at the master,then tighten it and let up on the petal.Do this several times for each of the 2 lines at the master, only cracking it when the petal is being held all the way down.Repeat...Do them separately.Have some rags below the master to mop up the mess and keep the master from running out of fluid. Then do the gravity bleed one more time on each wheel cyl. and watch for a bubble of 2.
I hope this helps you.
Yes the booster sounds fine.

The switch has a small plunger that has been pushed in too far. These are self adjusting units. You must pull out on the plunger with the brake pedal pressed, you will here it make noise as you pull out. This is normal then just release the brake and the pedal will set the length of the plunger for you. NOTE do not pull up on brake pedal, this will throw your adjustment off!
