Brake problems

[silvrmax04]

My brakes work great until the last fee seconds before a complete stop and then it feels like a sponge for a quick second. Kinda scary like they are gonna give out then grab again. Like an air bubble sorta. I have bled and bled to get the same results. Anyone ever have this problem or know what it could be. It seemed to start after I put a new caliper on one side. Forget what side but bled and bled. Idk it's been over a year and I don't drive it everyday.

bleed all the lines out starting with the furthest away from the master cylinder working your way towards the master

Mine does thee exact same thing. Bought the truck with 152,xxx now has 158,xxx never bothered me enough to look into the problem.

I'd look into swapping to braided steel lines, night and day difference. Just my opinion

My truck was doing the same thing. Found out it was the low speed abs sensor that was bad. Replaced the quick disconnect pigtail that attaches to the wheel bearing hub assembly and fixed it. The other thing you might be able to do is unscrew the end that threads into the hub assembly and clean it. This method didn't work for me but it's worth a shot

No CEL with the "low speed abs sensor" being bad?

Didn't throw any code for me or no code I could read with my autocal.

X2, very common thing

Thanks. Where is this sensor located? Is it only one total or one at each wheel?

Sometimes the reason the abs sensor is bad is the wheel bearing is also bad.
Just an fyi.
Sensor is on the wheel bearing housing.

Haven't had this problem but curious to see what you find. Mine are firm all the time.

Mine get 'soft' too. Seems to be the way they are. I have had the ABS module electronically bled off and that seems to work for awhile. Annoying more than anything. Maybe I will have to check into the abs sensors.

I did a flush of the hydro-boost system recently and it did a world of good for the soft pedal in my truck. I found a nice write up on another forum with instructions by accident when I was googling soft duramax brake pedal. Took me about 30 minutes or so total.

Link?

Link?

I wasn't sure how the mods around here liked linking to other forums. Some frown upon that.

Brakes nice and firm until the last 5-10' of a dead stop then it seems to feel like and air bubble in the line.

Probably rust on the ABS tone rings on your CV axles. I see it all the time at the shop I work at.

Mine feel like this sort of. I was told it was because my brakes are nearing their end. I would like a more firm feeling tho!

It's the hub mine did the same thing
