Don't know the solution but wondering how you discovered it? Did you get a flat?

When i stopped the car and hopped out there was that hot smell coming from the front end so i touched to see if anything was hot.

If you stop and can smell that a wheel is hot it is most likely because the brake is dragging on that wheel.
This is either from a broken return spring, a stuffed wheel cylinder, or (in my experience) a collapsed brake hose.

The brake hose might look fine on the outside, but the insides break down.

When you put your foot on the brake the fluid is pumped out under pressure to the wheel cylinder which moves the shoes against the drums. When you release the pedal, the brake fluid is supposed to be drawn back in to the brake fluid resevoir, but if the hose is breaking down inside it will collapse on itself and constrict the flow. The brake fluid between the constriction in the hose and the wheel cylinder remains pressurised, and hence the brakes drag against the drum.
That is very bad. The excess heat can ruin the wheel bearings, warp the drum and all sorts of other bad things.


Cheers,
Ray.

Yes, as benoz says, the brake can still sieze on with a disc brake front.

Brake hoses always seem to get ignored because they still look okay on the outside even when they are stuffed.

Cheers,
Ray.
