2001 Chevrolet 1500 Suburban Brakes/Front makes funny noise

make sure its not the brakes, also check the right side noise from the front can be deceiving

check brake pad. it must drum fitted.

2 probems here:
first one:
the belt bakeing on fast pull off you have a pully thats not turnig freely or at all

second:
GET SOME BRAKE PATS CLEANER AND TAKE OFF WHEELS AND SPARY THE CALIPER FRONT AND BACK TILL THE FLUID RUNS CLEAR, YOU PROB JUST HAVE BRAKE DUST IN THE SENSORS. IF YOU DIDNT CHANGE THE BRAKES THEN IAM 99% SURE OF THIS

it sounds like there is still air in the brake system that has not been removed.you don`t say if you replaced the brake pads and shoes(in which case you shouldn`t need to bleed)or you replaced a brake line(s) or wheel cylinder or caliper.you will have to keep bleeding the brakes all 4 wheels(trucks don`t use bi-directional braking meaning right rear brakes with left front and so on).bleed both rear brakes then bleed both front brakes,was this problem there before you replaced the brakes(soft pedal noticed) and this is why you changed the brakes or the pedal was soft and the brakes needed changing.its possible that the master cylinder has an internal leak and may need replacing.

YOU HAVE TO BUY FRONT PADS FOR FRONT BRAKES AND REAR PADS FOR REAR BRAKES THERE IS SOME DIFFERENCE.

Many drum brakes have longer shoe lining on the back shoes. Make sure you didn't put the shoes on backwards. The short lining should be on front.

check bearings

on disc brakes there is a metal marker on them that when the pads get low on material it will make a squeeling noise to let you know its time to change the pads.. so I would say you are in need of front pads also even though they look good you are getting low.. this marker is designed to let you know its time before you get to metal to metal .. jerry

it is almost impossible to solve without hearing it in person, but some things to check are the front brakes, front wheel bearings, tires, and loose suspension parts.

Have the front hubs and CV joints checked, that is where this kind of noise most commonly comes from.
