Alphas 2nd Gear July 21, 2014 Share July 21, 2014 Just noticed my brake lights is lighted after disengage hand brake. Went to buy some dot 4 brake fluid to top up. The light is gone, I didn't noticed any leak but should I be concerned? ↡ Advertisement Link to post Share on other sites More sharing options...
Joe6057 1st Gear July 21, 2014 Share July 21, 2014 Yes, there a leakage somewhere.. Btw, do u know whether your clutch pump share the brake fluid with your brake? It could be clutch pump faulty also which happen to me. Link to post Share on other sites More sharing options...

Alphas 2nd Gear July 21, 2014 Author Share July 21, 2014 My car is auto no clutch, but I intend to check brake leak in next servicing. Could be brake pad worn that cause this, so monitor see if the ! Lights up again. Link to post Share on other sites More sharing options...

QQDreamer 4th Gear July 23, 2014 Share July 23, 2014 high chance if your rear wheel is on drum brake the brake pump worn. its covered so you cant see any leakage . need to open up the drum brake cover to see if the pumps are leaking. Link to post Share on other sites More sharing options...

Count-Bracula Twincharged July 23, 2014 Share July 23, 2014 I'm having same problem and had my brake fluid topped up at Autosaver FOC. I need to monitor the fluid level just in case got leak. Thanks for the info. Link to post Share on other sites More sharing options...
Heartbreakid 6th Gear July 23, 2014 Share July 23, 2014 (edited) For KIA Forte/ Hyundai Avante, the rear brakes do consist of both disc and drum, but the drum brakes are mechanically operated and is only linked to handbrake, it doesn't require hydraulic fluid for operation. Brake pad worn shouldn't cause the brake fluid reservoir to be emptied too. The prime suspects are 1) faulty brake pistons 2) cracked brake linings 3) faulty seal between the reservoir and the brake pump. Brake fluid leaks tell tale signs are fluid stain on the surfaces, if you see those fluid patches, it's dangerous already. Piston faulty or the seal faulty within the caliper is difficult to see without jacking the car up to have a closer look. Please do have them checked and update us. Thank you.

Actually it ever happen to me. Brake pads worn down n the "Brake" warning light came on. I topped up my brake fluid n it was solved. Link to post Share on other sites More sharing options...

Thanks for the experience shared. Something to look out for as I always thought that the brake pad will have a warning pitch emitted, which is supposed to be a safe limit warning and not so much to an extend till the brake fluid went too low.

Alphas 2nd Gear July 24, 2014 Author Share July 24, 2014 The high pitch is due to a material scratching the disc as a safety feature. But everytime the pad is replace, the displacement causes the fluid to drain slightly. After a few pad change, the indicator for brake fluid may light.

You might lose fluid during pad's change due to leakage, however this is minimal and pads do last a long time. When you change to new pads, you have to push back the calipers which force the fluid back into the reservoir. Brake fluid level drops normally, bcuz the pads are worn thinner and the fluid goes down to "fill" its place. During the push-back, you might have to remove any excess fluid from the reservoir that you've added during previous "top-ups" Bcuz the level goes down due to normal pads wear, it is not recommended to top-up. If you have to "top-up" consistently, it means there is a leak and not due to normal pads wear. And topping up brake fluid is masking the real cause of a problem. If you have to change pads until the brake fluid light, it probably means you've overused the fluid and it is now in bad condition. Brake fluid should be changed out every 2 yrs on average as it absorbs water and lower its boiling point. Link to post Share on other sites More sharing options...

Just to update, the brake fluid was topped up and flush and refilled since I have not change the brake fluid for 5 years. Yes it is 5 years, and the numerous brake pad change probably caused some displacement and the fluid was drained slightly. After so many months, the fluid is still full and confirm no leak.

You need to change this every year or at most every 2 years. ↡ Advertisement 1 Link to post Share on other sites More sharing options...
