Suzuki Swift 2006 1.3 brake noise

Olwas2014

Hello,

When I have my 2006 Suzuki Swift in a stopped postion, handbrake up in neutral I pressed the brake pedal to test how it feels. For the first inch or so it feels like it usually does and i never usually need to press more than this. But as I am in the stopped position, I press the pedal more where it continues, but in a stiffer manner to the first inch or so I keep pressing until it nears the floor. Am I damaging it by pressing the pedal this much if I never need to press it this much while moving anyway? Anyway, when I release the brake from this fully pressed position it makes a whine noise which fades away once the pedal is pressed. I have uploaded the sound onto a youtube video. In the video with your volume turned up you can hear the brake pedal being released then the noise starts immediately Please find the link below. There is only 75000 km on the clock. I'm guessing it could be a faulty master cylinder hence the sinking pedal

Open the engine bay and check brake fluid level https://www.carcarekiosk.com/video/2002_Suzuki_Swift_GLS_1.0L_3_Cyl./brake_fluid/check_fluid_level
Is it low?
Can you see any traces of leaking?

The brake fluid is full and I don’t think there’s any leaks

Brake master cylinder failure is very popular in that model Swift and your symptoms are usually how it is first copped, usually during an NCT. When stationary, if you keep pressure on the brake pedal it will slowly go the whole way to the floor. The pedal should only travel 'x' distance and then tighten up, not keep going to the floor.

Shouldn't be expensive to put right and most garges would be familiar with it. Something i'd fixing asap though as the pedal will get worse as time passes and you will begin to lose stopping power.

It passed the NCT in september but I will have a look at the sheet in case there’s any advisory’s on it.

Thank you

It may not have been spotted at the time. The NCT isn't foolproof. Needs checking out though, it's not really safe.

I don't have to press the brake that hard to bring the car to a stop and the pedal never usually sinks unless i sit with my foot on it and press down while the car is stopped. Maybe I shouldn't have done that and put too much pressure on it but my stopping ability doesn't seem affected but I will check it out

Above is the link to a photo of the brake fluid colour (DOT4) is it too dark yellow or is it fine?

Just cause it is not affecting your stopping ability now doesn't mean it wont later. No use in waiting until the brakes dont work at all until you take it to a mechanic to look at. At that stage, itll be more than the brakes that need attention as you've been unable to stop when you need to.

Cars are/should be about maintenance and work to keep them safe, not wait until it's too dangerous first. You wouldn't wait for a tyre to fall off an alloy before getting a new one.

All this to say, any issue where the pedal is sinking should be seen by someone like a mechanic. It may not be possible to fully diagnose over the internet.

I'm not having a go at you OP, just nobody, including yourself, should be put in harm's way if it could have been prevented.

I haven't driven the car since I posted this just took it up a quiet road outside my house to test the brakes and after today I'm DEFINITELY bringing it to a mechanic. I even took a bus to work today - I don't trust the car until I get it fixed
