Hydraboost brake quirks??? Help please.
 

I just replaced the front calipers on my dually because they didnt seem to be working properly. If I stomp the brake pedal, it pulls to the right if i don't hold the wheel. When I start to drive again it feels like the left front brake is hung up a bit. For some reason the brake pads (brand new from previous owner) dont have clips that go into the piston, or clips that go on the back side of the caliper on the outside. What I don't understand is that the truck is pulling to the right when I brake hard. but the outside of the rotor on the right side barely looks like its rubbing. I really don't like these slide type (delco?) calipers, I would much rather have the bolt type, they just seem to slide better. With the caliper replacement, the brakes seem to be working better, but they're still pulling and acting strange. Any ideas or suggestions guys?

first thing to do is pull the calipers clean everything good. put the proper hardware on and lube everything properly. a bad brake hose will also collapse and cause the caliper to stay locked up. As i said first thing is to get the system mechanically sound and make sure everything moves freely

Replace your ruber brake line they brake down inside and acted like a check valve.

And after a while the let go and it drives fine? Am I right if so its more than likely that.

Ah Ha! That may be it then, great man, thank you! That's exactly what it's doing. It hangs up and then it frees up after a little bit.

That may also be the reason why they were such a pain in the butt to bleed after I put on the new calipers. It makes a lot of sense now, haha. I just hope that it IS the culprit.

It took me replacing the master, the proportioning valve (that was fun) before it I got back to the hose.I got bad ones from the part store.But now that the first thing I go to when I have a brake problem.

Fair enough guys, I guess I'm going to order some front brake hoses. Thank you all!

Do u get a strange vibration when driving on the highway?

Does the brake pedal feel strange?

Re: Hydraboost brake quirks??? Help please.
 

Not really any vibrations, the pedal feels a bit soft and then it will work. About 1/2 way down before it seems to work well.
