front end brakes

I have a 79 1/2 ton that swerves to the right when I apply brakes, can anyone tell me why? I have installed new brakes,calipers,booster,master cylinder, prop. valve. wondering if it could be the left brake line not getting enough fluid??

Re: front end brakes

First thing to do is a good bleed on the brakes.

Re: front end brakes

Sounds like you need to invest in new hoses. If that doesn't do it I don't have a clue.

Re: front end brakes

I agree with krue on the hoses, Sounds like the right one is collapsing internally restricting fluid flow under pressure.

Re: front end brakes

Hoses will do exactly what you've described once one has swollen internally.

Re: front end brakes

id still bleed the brakes good after installing the hoses and do both so you know both are good.. other thing is to make sure tire pressure is same and good in the tires and that all tires are the same size

Re: front end brakes

Yo Bro how you doing , checked out my 83 shop manual for brakes and it gave these things to check:
Restricted brake fluid passage or sticking wheel cylinder piston.
Air in system.
Sticking caliper pistons.
Sticking wheel cylinder.
Glazed brake linings.

Sounds like what everybody else has been saying, brake lines or air in the system In Visalia huh, glad to see more locals on the board 75 Silverstep is out of Tulare.

Re: front end brakes

If the truck is pulling to the right... your LEFT brake hose is more likely collapsing internally=replace. If you have the extra money... replace the the right side at the same time; you'll be doing it soon.
