Clicking sound when peddeling - GMC Denali 700C Road Bike

rusted together or throw out failure

Sounds like the engine vacuum drops, incase being a petrol engine. If it's a diesel, the vacuum pump might be worn out, and need to be replaced.

Hi there?
The brake light switch is faulty or is NOT secured. When the brake pedal is released it pushes the pin on the brake switch to switch the lights off. If the pin is not getting pushed in proparly then the lights stay on. check the switch. Good luck................

You have to have the engine running to bleed brakes

Your need a helper to push the pedal while you crack
open the bleeders

Have to do all 4 corners

Just not bleed,have air in system

Never needed all those parts & you didn't have
a clogged brake tube.

Sounds like you have a vacuum booster issue or a brake master cylinder going out. If you know of an independent mechanic the Vacuum Booster test is simple. It is recommended to replace both the booster and the master cylinder at the same time.

If there is one its under the dash someware around the clutch peddel arm, it should look like the breaklight switch with a spring loaded pin that pushes in or relieses out( depending on witch way its set up) when you depress the clutch peddel, or it could be under the hood, either way its got to work off the clutch peddel.

fuel pump if your lucky its just a dirty Fuel Filter.

It will take two people, one to push clutch peddel, and one to open bleeder, same as bleeding breaks, the person pushing peddel pumps peddel a few times and the last time holds to floor, other person opens bleeder to let air out, and then closes bleeder while peedel is still depressed, do this process over and over untill you get clutch or a steady stream of fluid with no air , while keeping an eye on fluid level in resavor.

Does it make a hissing noise when you push on the break peddel? or do you hear what sounds like a whiseling noise when its at idle? thats all signs of a vacume leak, it sounds me to be a bad vacume booster Witch will acount for you having to push hard on the break peddel, and it running bad when you step on the gas.

Chk. for vacume to booster, or loss of vacume like a break in vacume hose, do you hear a hissing noise when you step on break peddel. If you don't hear anything chanses are its the booster. When peddel gets hard to push you either lost vacume or booster went bad.
