Would your brakes smell like rubber burning if the master cylinder needed to be replaced?

It is possible that the brakes may smell like burning rubber if the master cylinder needs to be replaced. The master cylinder is responsible for providing hydraulic pressure to the brake calipers, which in turn apply pressure to the brake pads and rotors to slow down or stop the vehicle. If the master cylinder is faulty or damaged, it may not be able to provide sufficient pressure to the calipers, causing the brake pads to slip and generate heat. This heat can cause the brake pads and rotors to overheat and produce a burning rubber smell.

Here are some other possible causes of a burning rubber smell from the brakes:

* Worn-out brake pads: As brake pads wear down, they can produce a burning smell. This is because the friction material on the brake pads is made of a rubber-like compound that can generate heat and smoke when it is worn down.

* Overheated brakes: If the brakes are used heavily or for a long period of time, they can overheat and produce a burning smell. This is because the heat generated by the friction between the brake pads and rotors can cause the brake fluid to boil, releasing gases that have a burning smell.

* Leaking brake fluid: If the brake fluid is leaking, it can come into contact with the hot brake pads and rotors and produce a burning smell. This is because the brake fluid is made of a glycol-based compound that can vaporize and produce a burning smell when it is heated.

If you notice a burning rubber smell from your brakes, it is important to have your vehicle inspected by a qualified mechanic as soon as possible. This will help to identify the cause of the problem and prevent any further damage to your vehicle.
