Thanks! Will pay them a visit one of these days.
Are you using rear disc brakes? When I changed my front discs, I inquired about converting the rear to discs and the mechanic advised against doing so. Was just wondering if this is true, and if so, why.

well noted. but quite a setup for your braking system on your car. and semi slicks as well. may i know is the grip level very low during wet road conditions? what tyres and the size that you're using?
i believe your mechanic has his own reasons for saying that. but technically, i believe there is nothing against converting to rear disc brake. the problem is that you need to find the rear disc brake from some cars that fits to our kenari without much customization involved. also, u need to find a good fabricator to custom the brackets and stuff to mount the brake pistons and stuff and the mechanic must know what is he doing. unless you're transplanting K3-VET and going for higher horsepower thereafter, i dont think it is wise money spent to convert the rear drums to disc brake as myvi brake kit for the front will be more than sufficient for our EJ-DE engine. if you wanna further from there, once you have installed myvi brake kit you may consider to upgrade to better disc brake and brake pad.

Noted. He mentioned something about the handbrake not being as strong after a conversion to disc brakes, but I didn't ask for further clarification.

he is right, i also heard about this as well. Once you have converted to disc brake, the hand brake strength is not as strong as your drum brakes. technically, i'm not sure why. need some sifu for further clarification on this.
sorry for the super long reply...
whole conversion was actually done around two years back when i have no choice but to do it, rear brakes gave me problem first, realize it's not functioning and my mechanic suggest me to replace brake shoe, it works, but only last me one to two months before the problem came back. then after all kind of testing and inspecting, still couldn't get it done, i got fed up and forgot about it after some time...
i thought it's ok since front brake is still functioning until one day front brake caliper is jammed, my Ferodo brake pad finished in less then 10kkm. no choice i have to do something about it, got myself a set of Myvi brake set, totally plug n play into Kenari without modify anything.
was so happy until when i start to drive it hard and realize because the rear brake not working, the front locked up too easily even dry road. another no choice but to fork out few hundreds ringgit to get the rear to work, ended up with my current rear disc brake. the rear disc brake i get to bought is already converted to direct fit Kenari, modification was done by supplier, buy then plug n play.
currently my rear disc brake served as normal brake + hand brake. yes as you guys mentioned, it's not so good after the conversion, scared you to shit especially when the brake pad is new because it haven't run in. been running it for two years, i would say not too bad, still manage to park the car at slope with handbrake only, but don't think much people can put down the handbrake as i need to pull it to very high position. and also, car won't even slow down with just the handbrake compare to drum brake if using disc brake. i came to this summary:
CLARIFICATION on why handbrake on rear brake disc conversion not as good as original drum brake:
1. new brake pad. brake pad needs to run in before fully works. from my experience, give it a 5k~10kkm...
2. the end of handbrake cable X rear brake caliper is not allowed to have freeplay.
3. naturally handbrake by drum works better then disc.
i'm running on ATR K-Sport, two size available, 165/55R14 (stock Kenari size) and 165/50R15. i'm using the 14" Myvi SE rim. if you're into real performance, get this tire, but, life spend of this tire is half or even lesser then standard road tire. i had a pair changed on early of March this year, another pair on July ago. one of the pair need to replace i think around CNY next year
CLARIFICATION on semi slick tire
1. it's legal (because no one say it's not illegal).
2. semi slick is alright under the wet condition, with three condition: 1. keeps your eye open real big, don't drive over standing water puddle on high speed, let say 60km/h on 1" standing water puddle? 2. tire thread is used to expelled the water from beneath the tire, it works the same like standard road tire, without tire thread either on standard road tire or semi slick, you're in deep shit. so don't put the blame on semi slick. 3. ask me on TT
again, sorry for the super long reply...
