Yes and no. Let me explain

Yes: Many D segment and higher cars have all discs, (e.g. Altis, civic ..., even the old City VTeC).

No: The problem is that more effort is required to get a decent hand brake, as the drums have an self clamping action. Some cars even have inboard drums for the hand brake only.

No, it cannot be of TVS Apache as the disc size itself is different (front 270mm and back 200mm petal shaped), the positioning of clamping holes are different for cars and bikes. In this case may be the quality of material used is different.

Not entirely convincing an argument. Cars too have similar diameter discs up front for one. Two, the pads need not match the exact shape of the disc area in contact. Some units of late on high end bikes use square/rectangular pads per piston rather than single pad for each bank of pistons , regardless of disc diameter , though the usual application means the ballpark disc sizes are not much different ( 300-320mm for most SBKs ).

I got back the bite, smoothness as well as the play in the braking system.

Hence, for all those who replace their pads, please ensure that they are original and intended for your car make/model.

Hello paragsachania

Just to clear this up. MSIL has multiple vendors for a component for most of their models (except very low volume ones like SX4).

TVS Girling, as you correctly mentioned is Brakes India. 'Apache' written on your new set of pads has nothing to do with the TVS motorcycle though.

Apache is a grade of pads from the other vendor - previously KBX, then Bosch India and now FBIL (Foundation Brakes India Limited), Pune. Hope this clarifies.

Why do disc brakes in bikes have holes whereas those in cars dont have?

[sudev]

Higher end or performance disk brakes also have holes. Helps is fast dissipation of heat resulting in better brake performance.

There are also grooves to throw out water so that friction is maintained at highest levels.
