Brake line for 94 Chevy S-10 pickup

heck thebrake fluid level before you go any further ,

What kind of "dinging" noise? Do you hear it whenever the car is moving, or only when you apply the brakes? When you changed brake pads, did you bleed the brake system? If it wasn't bled properly, that could activate the brake warning light.

First thing to do is check the level of the brake fluid in the master cylinder reservoir.

sounds like the flexable line close to the wheel is bad.
it has plastic inside it and when they get old the plastic breaks apart and plugs the line.

Check the reservoir under the hood.

The brakes making noise has nothing to do with fluid level, though.

There's a good chance your brakes are glazed from overheating or they are in need of replacement. There are sometimes pieces of metal which rub the rotor and make a loud squealing noise when you press the brake - they're wear indicators.

there is a sensor on the brake pads on bmws that check for noise and when the sensor hears noise it is telling the car that the wear indicators on the brakes are hitting and causing noise because the brake pads(lining) is low,means check your brakes the pads are low and if you dont check them soon you will have no pads left and my grind the pads metal to metal against the rotors,so all it is saying is you may need new brakes because they are worn out
hope that helps,,,

The noise you hear is normal when it's time to change the pads. After you've purchased your brake pads (usually $20-30 depending on where you go, quality, etc), take your front tire off and take the 2 bolts out that hold your brake caliper on. You should be able to lift the calipers upward above the rotors and remove the old pads (they just snap in). Be careful not to put too much stress on the line connected to the calipers as these lines are full of brake fluid. Breaking or cracking this line is not good. Just hold them in one hand as you change the pads. When you put the whole thing back on the rotor, you'll need to compress the pads, otherwise they won't fit. I usually use a long screwdriver and pry the pads back. This will ensure you will be able to match the holes up for your two bolts to go back in. Repeat on the other front wheel. Hope this helps.

Rubbing noise usually indicates that your brake pads has worn down, and it's rubbing against brake rotor. It's more like grinding noise rather than rubbing, right? And for the brake light problem, as brake pads wear down, brake fluid level goes down too. Your car is equiped with a brake fluid level sensor. So, check your brake pad first before adding brake fluid.

have one person in the blazer pumping the brake pedal and then hold to the floor, crack the bleeder then tighten, release pedal, repeat till all air is out one side at a time, if this does not work then your ABS unit is bad witch if u follow your lines from your master cylinder u will find a black box with a motor on it, or the master cylinder itself is bad, it also can cause u to have no pedal, replace the master cylinder first, most likely cheaper.

Look at the master cylinder fluid level. If it is low, the red brake lamp will come on. Note that as the front brake pads wear, the brake fluid level will drop proportionally. If the fluid level is indeed low, you may need front brake pads, Unless you have a lot of miles on it, I doubt that you will need rear brake shoes. Also, if the fluid is low, don't add any. When you DO have to replace the pads, the additional fluid will be forced out of the cylinder and get all over your engine compartment under the master cylinder area . Brake fluid will eat the paint. Check the brake pads, replace them if the pad material is worn.
