Anybody ever done the project above?

I need advise from anyone who know or ever done before. Can if be done with normal tools like wrenches, plyers, screwdrivers without workshop tools?

What are the things I need to get? Before this, I thought it is the disc brakes set only. Then the workshop guy told me about knuckle. What is this knuckle thing? And can we just change the drums to disc or have to change the whole suspension set up?

By the way, my car is a humble ae111. Thought of changing to the AE111 GT rear disc.

well if the disc set comes along plug n play to your rear arm...then it shud be easy to DIY...

what makes some rear disc conversion dificult was to fabricate caliper bracket....

Oh I heard it is plug and play. So let's say if it is plug and play, what are the steps?

1. Disconnect the drum nuts
2. DC the hand brake cable
3. DC the ABS sensor
4. DC the hydraulic cable
5. Then just fix in the discs and plug back all the cables in?

any steps missed out? How to dc the hydraulic cable without spilling the fluid?

final step would be bleeding the unwanted air from the brake hydraulic line.....


this one u might need some help to pump the brake.....


p/s:the brake fluid would spilled a bit...but don't worry..topup accordingly during air bleeding step....

I have done this DIY without any special tools or air guns,but you need a good leverage to untighten the tight knuckle bolts and nut.The knuckle is interchangeable between the drum and disc.The hard part is the handbrake cable... other than that,should be no problem..lot of the part is interchangeable so you can compare it after you dismantled the drum.

you need to change the whole knuckle with disc because your brake caliper won't have places to bolt on to.

as like bro "cuscostrutbrace said. the arm link was shareable between drum type and disc type brake system as for AE101-110-111 models~ it shouldn't be a problem changing them. The only concern later was the master cylinder was a bit diff between the two. it's 17-11 for the drum and 17-13 for the disc if i wasn't mistaken. Disc type piston need more brake fluid to function. ^^ should take note about it.

just my two cents (V) ~ ^^

for your reference. If it's understandable~ ^^
Whoa! Thank you thank you! That is clear and I understand now. Okay... That is for the front. But if I were to do a rear drum brake to disc brake conversion, is there still a knuckle? Because no steering ma... So still got this knuckle problem or not? Or just plug and play the disc?

Thank you...

there's still a knuckle. Just the way it links is different. The front strut needed to steer so it's sits on a ball joint on a lower arm so it count turn when your steer. As the rear didn't need to work so. It is linked to the chassis by (normally) 3 bars in AE111's case. One torsion bar and two link bar. You just need to unscrew these 3 bolts from the drum's knuckle, then you will see the disc knuckle should also had the same 3 'hole' to screw on the 3 bolts~ as the handbrake cable and hydraulic hose, you should know how to did the job ;)
happy fixing~

Yeah the AE111's rear suspension is a 3 link. Wah sifu you expert in AE ah? You play AE too? Well if it is so simple like what you say, then I guess can DIY. Last question, so means that the rear knuckle can use back right? I just get the disc and caliper set.

not really expert la ^^ just having fun working on my AE92 for 5 years already, lol~ the original drum's knuckle would fit the links, but if i'm not mistaken the wheel's bearing won't fit. So you still need to get the whole knuckle~ for my concern, taking up the whole knuckle won't cost you much extra bucks~ hahaha~ to save the trouble, take the whole package.

P.S. handbrake cable is diff, take it as well~

When I change rear drum to disk few year back, I've noticed interesting method that foreman used to bleed the brake fluid. (He's a senior foreman). While changing the rear disk, he just left the brake hose to bleed by gravity, so that by the time he finish changing the rear disk the hose will be full of fluid. So it can be one man job. No need assistant to pump the brake.

If we remove the camber nut we should realign the camber right? I donno what he did because after I check with alignment machine, there is no need to adjust the camber. Respect la kat foreman tu. Already save RM25 per side for camber alignment.
