It's better to check for your braking system for the spongy feels. But Persona CM has been associated with spongy brake AFAIK.

Leaking master pump is one possibility but you should be able to detect the leak at least from reducing braking fluid level.

Another possibility is characteristic of your brake pad, it will feel soft if it's soft type. I have changed to metal type and the feedback improved, yet the screeching before reaching operation temperature during morning drive is just annoying.

Jammed calipers usually changed one shot when you change brake pads.

Maybe you should inspect braking line as well for potential swelling when you brake.

All in all, get a trusted workshop to check. Better than guessing in dark.

Ill have someone looked at it.

I think my brakepad is Proton brand. not sure is the softer or harder type

Didnt know the thread still so active.
2015 sv owner 190k km service this friday.
i still go sc couz lazy to track on my fluids.
Mechanical parts alot done outside

changed
1) mounting, stering bush
2) drift shaft
3) front absorber, absorber mounting , stabalizer link(i think)
gone one question, my break sometimes feel lembut after long driving
Master pump?

I recently just change brake fluids, its better but still abit lembut SOMETIMES.

do we need to service brake calipers?

Get a professional to check the brake lines. If nothing leaks, probably just your brake pads.

I used Brembo semi metallic brake pad for a short while. It was not good because how inconsistent the braking feels. When the brake pad gets hot, I have to hit the brake harder.

Hi guys. Have a little question here.

I noticed the radiator top coolant hose on my car have a bit of leak. Bit of coolant can be seen hardened around the hose. The mechanic used a lot of grey RTV Silicone around the hose, the coolant leaks around the silicone area.

Been like this since last April. My car is not losing coolant.

Sometimes after a long drive, I can smell the sweet smell of the coolant.

Should I get this fixed as soon as possible? I'm planning to get it fixed together when changing the timing belt and water pump when I got the time.

Mine leaked from the thread part of hose. As long as you keep top up and wash away the solidified coolant, as well as pay close attention to temperature and leak severity (mine getting worse over time) i think it should be ok to drag until water pump change. Depends really on how fast they detriorate.

Ours is small head with 1.1 PSI, right? I will check the price with Proton & OEM, if not much different, then will go with original.

I didn't chane at the end. Went to Proton SC, the mechanic so nice, bring the cap to my car want to change for me, after he tear off the sticker looks dry, then tell me no need to change unless overheat.

Was thinking is it due to hot weather? so many heat issues on old car.

Still it happened. Maybe what you can do is monitor closely by installing an OBD monitor on water temp.

Touch wood so far so good. Just wonder quite number of people & few cases also relate to heat issues.

My is idle vibration still not good, some times can feel like short of breath. This happened after change thermostat. Last major service, change ATF, spark plug, air filter, fuel filter and even spray to clean the throttle body but still not improving. Give up already, maybe last is engine mounting.

78°C or 85°C thermostat? For car that old like ours, might need to check ignition coil also. The ignition boot of campro IAFM cracked easily and can be replaced cheaply.
Final thing about it is heat. If you can identify coolant temperature range when breathlessness occurs, it'll be helpful.

Based on my record, i changed once at 77k, now is 150k. What's your mileage when change mounting? I did change once as well at 94k, don't want change so soon, not sure how long this car can last...

78°C, how to check the ignition coil?
Mostly on idle, sometimes obvious sometimes ok, when drive is normal. I just monitor see getting worse or not? My current pending issue is Alternator pulley, start getting some minor noise on idle. Check with few foreman some say change the pulley after market, some say no issue, just the noise won't impact anything.

My current mileage around 107k still on original mounting, already earthquake feeling but yet to change.

Recently the radiator top water hose attaching to engine side got minor leaking, can see reservoir tank level dropped to minimum. I tried tighten the screw, but it gone loose again in just 1 week. I see the screw end very near to the timing belt area, so last week tried loosen and tighten again and move around a little bit, hopefully fixed it.

Theoritically you need to check for misfiring with scantool. But then when my spark plug gone case, there's no such code also hahahahah so maybe our persona don't have sensor for it.

There's only so many things that can affect your combustion. For fuel, air and spark you more or less settle the wear and tear items already. Maybe it's wiser to keep close watch before spending money in blind trying to fix it.

In some car, faulty ignition coil pack will have overheat white spot. I doubt ours will do that. Commonly spoil for that part of system is the coil boot. Everytime i change spark plug sure one or two koyak. And leaky boot sometimes as per my mechanic said might cause the current to leak out via ground, instead going to spark plug. But still, it won't affect drivability, just some drop in performance and owner satisfaction.

Ya could be, will monitor and observe. If leaking can see the coolant stain and reservoir level dropping.

to be honest not much. after change than know its very low vibration.

i generally drive quite alot in terms of milleage.

2015 car.

today just done EO,ATF,coolant,fuel filter, brake service at proton sc haha
im a lazy man.

EO at proton sc quite cheap fully syn around 160?

How much to change timing belt and water pump these days? Time flies so fast, already 3 years since I had mine changed. Last time I was charge RM500 for parts and labor.
