Ok, my brakes have felt the same since I got the truck. I push a little harder that I should have to (not a hard pedal, but further to the floor than normal to where it's harder to push) get the truck to stop. If I want to brake check someone that's riding my bumper I have to REALLY smash the pedal and even then it doesn't grab hard or lock up. Since I have owned the truck I have put all new pads, rotors, and calipers ( https://www.summitracing.com/parts/p...odel/excursion ) on, Russel braided lines front and rear (all 3 on the rear), and flushed ALL of the old fluid from the truck (Twitch and I went through 2 large bottles when we did the brakes).

After all of this there has been no change in my brakes at all. Not one bit. What's odd is sometimes after it rains when I first get in the truck the first time I stop I get massive awesome brakes, but just the once. So any ideas guys?

I never have a spongy pedal, and I never lose pressure, I just have ****ty brakes.

 

Well, it is an 8000# vehicle. That said, I just finished the Powerstop upgrade that I started in October this past weekend (front in October, rear in March), and I couldn't be happier.

I had a similar problem in a Bronco I used to have. Was a bad master cylinder. Tried bleeding it and it marginally helped. After replacing the master cyl, the brakes were great.

 

The MC is the only thing left really, but I was really hoping it wouldn't be that.

 

With ABS, I don't think the Ex has a proportioning valve. Besides the master cylinder, the ABS module itself could cause symptoms similar to what you describe.

I think you'd rather change the master cylinder.

 

what engine ?
if diesel i would look at the hydrboost and powersteering pump.
for hydroboost contact vanco

on a gas engine check your vacuum brake booster.

 

Seriously??
Wikipedia even knows Apoc has a V10, previously had the 5.4, drools over the thought of a PSD.
LOL, so many threads from the past about his hunting for a new Ex, etc.
I think I know more about him and his wife than some relatives.!!

 

+1

Pirate must be new around these parts.

It could also be the booster. Try this:

Get in the truck and pump the pedal up 3 or 4 times. Hold it down and start the truck. Does it sink down more or does it remain at the same height?

 

Damn you wikileaks! The truth is out!!!!

 

Have you tried activating the ABS? Maybe find a gravel road and hit them hard so the ABS activates. Otherwise I would bleed the system again. You can try running a house from the farthest caliper to the master, moving your way forward, this should help bleed the air from the system and master cylinder.

 

Apocalypse I can`t even believe this is how you would explain how your brakes aren't working properly!

 

We just all know how "special" he is.

 

uhhh, stalker!

 

IDK, it gets the point across...

 

^^^^^^ This, an air bubble in the ABS can even cause similar issues... PITA to get out.

 

We have a lot of "low speed" areas around my town. If it says 25, I do 25. I'm from Smith County Texas, it's probably the worst jurisdiction in the US... seriously, books have been written and people have been killed/framed by police. I'm super cautious when I drive and when someone rides my *** for 2 blocks or flashes their lights at me I don't do that "Fine, I'll just drive slower" ****, I just brake check them. Sure I've had a few close calls, and sure I've even been hit once or twice, but I've never had any damage done to my truck
