Brakes pulling to one side
I am sure that this has been covered but really cant find what i am looking for so any info will help.
Replaced caliper, pads, rotor, and still will almost put you in a ditch. What be the deal? Prop valve? MC? or brake lines. It is not sticking, when you put the brakes on the drivers side front disc will grab harder and pull you into the other lane. I have done what i know. |

Re: Breaks pulling to one side
I agree with rodman, the brake hose is more than likely plugged shut on the passenger side. Very common problem, the old rubber breaks down and swells shut.

Re: Breaks pulling to one side
Sounds like you are getting very little pressure to one side. I would check the brake hoses and lines on the side that isn't grabbing.
My guess is either a blocked line; or maybe even a flexible line with a bubble in it, when you hit the brakes the fluid expands the line and doesn't make it to the piston. I would lean towards the blocked line. Did you notice any problem getting fluid when you were bleeding that side?

Re: Breaks pulling to one side
The brake hoses collapse internally. (You won't be able to see it)
Ususally the side that pulls is gettin ALL the fluid, and the opposite side is collapsed. I'd replace BOTH hoses. EDIT: I type too slow,...

Re: Breaks pulling to one side
I'd agree on the hoses. Along with that I would be checking the steel line to the right front wheel to make sure that it had not gotten smashed or twisted somewhere. Check every inch of it for damage.
And yes, replace both hoses when you do it. Last edited by mr48chev; 02-22-2010 at 12:34 AM. |

Re: Breaks pulling to one side
Hoses. Just replace them both (go back a few weeks ago and you'll see I was in your very same shoes). They're cheap and readily available at any of your local parts stores. Cnut

Re: Breaks pulling to one side
I've had this happen to a friend of mine. If its not the hoses its the prop valve. From what he was told theres a difference in drum and disk brake valves. His was yanking him around pretty good too, swapped the valves and it evened out. Good luck.

Agreed, front brake hoses!

Re: Breaks pulling to one side
Quote:
When you truck is pulling to the left (driver's side), safely pull over to the side of the road. Then VERY carefully, see how hot the wheel and hub on the RHS of the truck is. What can happen is if your right side brake is hung up it will get hot and fade. Then when you step on the brakes, that side doesn't grab and you pull the other way. If the RHS is hot, start with a new caliper and set of pads on that side.
