In my experience on our delivery vans, the entire clutch assembly should be replaced. There was a time where we just replaced the release bearing
after some time, just a year we have to open the transmission to replace the pressure plate. so lesson learned replace the entire clutch system.
clutch disc, pressure plate, release bearing and pilot bearing. check clutch operating/secondary and clutch master for leaks. You can use made in japan replacement, I think the best is Aisin, also used for OEM.
What we usually use is Exedy for its accessibility from our supplier.

I think with the ertiga its unusual, ang bilis naman masira ng release bearing, sa mga L300 usually abot ng 100k km bago masira sometimes more pa. alam mo naman paano gumamit ang delivery.

gamit naming release bearing basta made in japan. NTN, Koyo I don't remember the other brands but tumatagal na siya as long as the disc.
