2. Brake cleaner - Wikipedia

   en.wikipedia.org/wiki/Brake_cleaner

   Non-chlorinated brake cleaners use hydrocarbons as a main component; it will either be a low-boiling aliphatic compound or higher-boiling hydrocarbon mixture. Aromatics like benzene, toluene or xylene may also be used. [6] The hydrocarbons used are sometimes made by hydrogenation from naphtha. The lipophilic liquids dissolve fat-soluble ...

3. Tetrachloroethylene - Wikipedia

   en.wikipedia.org/wiki/Tetrachloroethylene

   It also has its uses as an effective automotive brake cleaner. It has a mildly sweet, sharp odor, detectable by most people at a concentration of 50 ppm. [6] Tetrachloroethylene is regarded as a toxic substance, a human health hazard, and an environmental hazard.

   Brakleen, a tetrachloroethylene (PERC)-based brake cleaner, is one of CRC's signature products. It has gained a cult following due to its dissolving power and has been used off-label for many other purposes, a practice strongly discouraged by health experts and the product's own warning labels.

   The brake soak is a 25-foot wide circular water trough containing a 5% slope on the outer edge to allow immersion of only half the vehicle's braking system. Gravel Durability Course: Level 2.6-mile (4.2-km) Gravel Durability Course provides a series of twists, turns, and straightaways.

6. Trichloroethylene - Wikipedia

   First, ethylene is chlorinated over a ferric chloride catalyst to produce 1,2-dichloroethane: CH 2 =CH 2 + Cl 2 → ClCH 2 CH 2 Cl. When heated to around 400 °C with additional chlorine, 1,2-dichloroethane is converted to trichloroethylene: ClCH 2 CH 2 Cl + 2 Cl 2 → ClCH=CCl 2 + 3 HCl. This reaction can be catalyzed by a variety of substances.

7. Brake fluid - Wikipedia

   The brake fluid in the tubes, in turn, pressurizes the brake slave cylinders, which are on each wheel. [22] [23] The slave cylinder pistons press down the brake pads. They encompass and compress the brake disk, and the rotation of the wheels slows down. In addition to transmitting pressure, brake fluid also keeps the brake system working optimally.
