You need to check your oil, sounds like you are dangerously low!! Be sure to check it to see how low you are and then add the needed amount...
STICKING BRAKE CALIPER
As the brake pedal is pressed, an attached rod on the master cylinder applying pressure to the brake fluid in psi. This pressure is applied to the calipers/wheel cylinders clamping the brakes. In front brakes(disc/caliper) setups the pressure is multiplied. An example: Applying 100lbs of force to the master cylinder(not the pedal, since the pedal has a mechanical advantage of 5-7:1 meaning 20lbs or less on the pedal is 100 on the master cylinder). Because the master cylinder's piston has an area of 1 square inch(generalization) it would equal 100psi. 100psi of pressure on the caliper's piston which can have an area of around(say) 3inches, would exert 300psi of pressure on the pads.n disc drakes
Normally this is caused by warped brake rotors.
I would advise bringing your car to a mechanic as quickly as possible. Your brakes could fail. This puts you at a high risk for injury or even death.
excessive shaking when applying brakes points to brake rotars being out of round, cracked or warped. have rotors machined
This could be for a few reasons, but if they are getting hot without you applying them, I would suggest that they are sticking and causing the pads to rub on the discs, or if they are drum brakes, the shoes on the drums. If they are only getting hot as a result of using the brakes, I would suggest checking that the brakes are balanced properly, and that the front brakes are not doing all of the work/ or that the back brakes are working at all.
You would have a leak in the coolant system somewhere and you need to have the system pressure checked.............
Bleed the master cylinder.& then rebleed the system.
One would not be able to operate Turin Brakes under high pressure as they are actually a folk band from Balham, London. There are 2 members in the group.
brake pads could be worn out. would it be safe to drive for now if the front brake pads are ok?
Most air brake systems are fail-safe. This means that if there is a failure in the pressure system the brakes will lock on. You need gauges to show that you have sufficient pressure to proceed and to know your brakes are not dragging as this would cause them to overheat.
Possibly warped brake rotor/worn brake pads. Get this checked out.
