In this BLOG I am sharing the Picture of "Under Wheel View of High Speed LHB Coach" used in Indian Railways. You can see that LHB Coaches also use "Brake Discs" or "Disc Brakes" like the High Speed Locomotive WAP-5 used in Indian Railways. But the concept of Disc Brake/Brake Disc is slightly Different in case of High Speed Trains. It is enumerated below:
Disc...
more... Brake
As used on trains, the disc brake (photo left) is similar to the disc brake used on road vehicles but may take the form of a pair of discs mounted either side of the wheel web or a double-sided self-ventilating disc mounted on the axle. Very high speed trains, such as the French TGV, have up to four sets of double discs per axle. The design and number of discs is critical to train safety as they must be capable of dissipating the maximum amount of heat generated during an emergency brake application from the highest speed attainable by the train. Disc brakes on trains are invariably air operated.

Brake CalipersHere also I explain the Concept of "Brake Rigging" which is very important in case of Electric Locomotives like WAP-4/WAP-5/WAP-7/WAG-9 etc.(Ref:/blog/post/1598885)
Brake Rigging :
The means of distributing the braking forces from a brake cylinder to the various wheels on the vehicle. It consists of rods and levers suspended from the underframe and bogies and linked with pins and bushes. Rigging requires careful setting up and regular adjustment to ensure forces are evenly distributed to all wheels. Badly set up rigging will cause wheel flats or inadequate brake force.Brake rigging is now only found on older vehicles where there may only be one or two brake cylinders. More modern systems usually employ one brake cylinder per one of two blocks or per disc.
Here also I discuss the Concept of "Parking Brake" used in High Speed Locomotives like WAP-5/WAP-7/WAG-9 in IR.
Parking Brake:
The Parking Brake, used to hold an unattended vehicle when the braking system is shut down. Often referred to as the 'handbrake' where it has to be manually applied on each vehicle as opposed to the automatic application provided on the most modern vehicles. Not all vehicles are equipped with parking brakes.
