Rm8k Wira & Jazz GK5 ownership experience-A long way to go

[minibeany]

That's not normal. Wira brakes are generally pretty good in stock form.

- Service the brake servo and change the master pump and stick with ori. Upgrading to Evo pump is fine and all but you'll need to relearn how to brake as the pressure is significantly greater with the Evo one. Some people said it results in "on/off" brakes.
- Any Wira will be damn old so change all the brake lines to steel braided lines. Ori rubber lines will be so soft it expands very easily.
- Change to good brake pads. Avoid pads like metalking as they only bite after they warm up. Cold it's pretty useless.
- Consider upgrading to GSR calipers. The oil channels inside the GSR caliper isn't that much bigger than stock Wira so pedal feel doesn't change much. But the piston is much bigger so you get better bite.
- Upgrade the rears to discs from the Satria GTI or Putra. If you do this get both front and back if you haven't already bought the GSR front. GSR rears need some modification so avoid.
- Use DOT 4 or 5.1 oil.
- Flush your oil system and ensure there's no leak.

Evo pump is too much. It will be like On/Off like what you said. Tested one of the unit at the workshop. Not my taste.
i'm planning to change to braided hose.
can recommend good brake pads? Use Trestor before. It has a lot of dust.

You want dustless over performance. If used in mostly city drive then Bendix General CT will do. CT is Ceramic Technology, good for cold bite but cannot withstand too high heat as these are entry level pads. Metal King like bro. Izso mentioned good when hot will also be dusty

had e3 brakes on my saga... not great.

the brakes originally on the car were imo not great in a pickle but with the e3 pump, it bit way too hard. You do get used to the way it stops so you will learn to feather the brake over time but, in a situation where you panic and suddenly slam on the brakes, you will lock up.

There's lots out there. Try them all and find the one that suites you. I personally like Trestor advantage, Ferodo Zero, Ultrex and EBC ultimax.

cold bite suits me. Always short drive and low speed. thanks all.

BTW, where can I but Pro-RS braided hose? Can recommend a genuine seller?

7 years ago for my Mark X I bought at Kakimotor Sunway coz they offered the best price I could find back then but nowadays I find them more expensive. So for my Swift Sport last year I bought at SpeedZ Icon also in Sunway, much cheaper. Try also ask Rev Performance in Sunway also, they usually can give competitive prices.

EBC Ultimax are the black pads, which are OEM replacement only. Next higher should be EBC Green

Since I got it so I juz put aside 1st. After checking everything is fine. If I swap the drum brake to a wira & putra rear disk brake is it ok?

Satri GTi is easier to find. Big and nice on the rim. Make sure you have 15 inch and above.

Slow and steady lah...later from daily ride the car becomes a project car....heheh

Dont forget to check all water hoses and that include the steel pipe which runs under the exhaust manifold which tend to leak and kinda hard to replace. Go for ori pipe as cheaper parts are just cheap in term of everything. Once done dont be stingy and uses tap water in the cooling system. Be a macho man and used 100% branded premix coolant.I am proud to say i am macho with my BLM and Waja and Pajero...hahaha.
Its worth it in the long run, trust me.
Last time i tend to use only one bottle and top up with water.

In term of contact surface, drum brakes are better than disc but the main problem is heat dispersion. My 2 ton Pajero is using drums as the back but it still stops beautifully coz its well adjusted. 2 click of the handbrake is all thats needed to stop it from rolling back at an incline.

Service the current drums brake first, get it properly adjusted and u are good to go. When i adjust the rear drums i always allow a slight..very slight drag on the drums when the handbrake is down. This way braking is a lot better in term of response.

Will do so.After my friend know I bought a wira he starting to brainwash me 4g93T swap. I was like no $$ no talk lah. But luckily I haven't mod my jazz.

Ultimax is plenty for street use. I tried them before and with the way I brake they don't fade either.

Actually - if you mod supporting mods like suspension, brakes, handling, you might not need the power up. Cuz a nimble car is more fun than a car that just goes fast straight.

I DO consider swap a set of new Front & rear lower arm since they are not very expensive and they do improve handling & ride quality if I am not wrong?

After finish up brake my plan is do swap a set of Gab SE series fully adjustable since they are not bloody expensive like 1.5k something. Juz step by step.

And 1 most important thing. Dash cam!!!
Last time my myvi kena hit by a lorry luckily I got dashcam. Go inside polis station meet Sargent didn't stay for 5minute come out already. Bcoz dashcam say it all.

Only if the existing ones are worned & making noise.

Since you're driving to long distance better to ensure the pipe and temperature is in good condition. Car at this age is prone to temperature sensor issue. It took me a while to fix that. I was not able to drive at all. Temperature started to rise once I'm caught in traffic jams. Air-cond cut off and blowing hot air. Ended as what gunnerzz said, I changed all the pipes, service the radiator (full of mud) and change a temperature sensor too.

Agree. Enjoying the slow ride.
