Unhappy Soft brake pedal

I am new to the message board and am seeking some help with a soft pedal brake problem that I cannot seem to solve. I recently installed the SSBC front rotors and pads along with new calipers (01 DakCC 2wd with rear antilock) and even after bleeding the brakes several times, still have a soft pedal. The ABS and brake lights are not on. If I slam on the brakes at speed, the fronts will not lock up like they did before the brake job.

I have done many brake jobs in the past, but never had a problem like this. Any help will be appreciated.

if you are sure all the air is out of the system, then try adjusting the rear drums....?

I know you said you've bled the brakes several times and you're no rookie to brake jobs, but it still sounds like you have some air in the system in the front. Sometimes it can be a real bitch to get out. Just my .02!

Soft brake pedal

Thanks for the advice. The 7 yr extended warranty ran out a couple months ago, so I will be doing most of the repairs now and will definitely be referring to this site. I hope I will be able to help others as well.

I will bleed the system again and tighten up the rear brakes. I know that even a small air bubble will reduce braking power -the problem is finding it.

Thanks again

Pete

Any new caliper is full of air and it can be a PITA to get all the air out. You can either let it gravity bleed or use a One-Man Bleeder so you can watch to make sure there is no more air.


When I did the calipers on my Durango, I shit you not I went through about a 1/4 of a big bottle of brake fluid before all the air was out.



Quickly read the post above, as it will more than likely be deleted within the hour.

It could be that when you bled the brakes, somehow the master cylinder went out on you as well. I have seen thea happen from time to time. Just an idea to toss out there. Good luck.

I would like to know what you figure out about your truck.

Thumbs up soft pedal

I bled the front brakes again (gravity bled) and ran about 1 pint through each caliper, then test drove the truck. No change. I then adjusted the rear brakes as advised - i had to crank the star wheel about 4 times per side through the backing plate. Test drove again and I definitely have a higher pedal ( no surprise) and it does feel a bit firmer than before (still a bit mushy). I might try bleeding the entire system again and see what happens.

I have not noticed any of the classis symptoms of master cylinder failure, buit will keep that possibility in mind. You never know!

In the process, I noticed that both front wheel hub assemblies are a little loose (I was getting a little bit of a whine the last week or so). I ordered all the parts (including the non re-useable retaining nuts at $14 a piece from mother Mopar), so I have another repair session with the Dakota this weekend. I found a few other threads with lots of good info on the hubs.

Thanks, everyone, for the helpful advice. Much appreciated.

get yourself a set of speed bleeders. They are worth the $20 it will cost you for a full set. They make bleeding easy, fast and a one man job.

When in doubt, gas it. It will either fix the problem, or at the very least end the suspense. (Ironically this motto had nothing to do with this)

Two words...Master Cylinder. You have done everything else that anyone has suggested. When you bled the brakes and the person or you had been pumping them up had worn out the cups inside. Is normal if you try to bleed brakes like that. Have seen that happen many times. Trust me. Have a nice day.

I think you are right about the master cylinder - it wouldn't hurt to give it a try and it is a pretty easy job to put on. After bench bleeding the new M/C I will try the one-man bleeder. I actually have one, but for whatever reason never used it.
Thanks again - will let y'all know how it turns out.
