I've heard of where "goes to the floor" creates trouble as the usual travel wears down the piston and rubber and then when you push to the floor it can create troubles in that area. Which is unrelated to the brake grind.
As to the brake grind my usual mechanic will take it apart to see what's up, replace what's needed and it's fine. Only had this happen a few times over the decades but it's a common area that needs repair. I'm most concerned about the goes to the floor story.
Hello. I’ve been having problems with my Suzuki swift 55 plate since I got it in August.
It began within the first week, where I broke quite hard and then my journey all the way home after that the brake would go all the way to the floor. It stayed like this, went to the garage next day and got new rear adjusters but they still felt dodgy. Bled the brakes and changed brake fluid couple weeks later and they went back to how they were originally - perfect.
However, 4 times I have been driving and randomly there is this grinding sound and the break pushes down slightly but I feel this grinding on my foot for a good 2 seconds and the car sways and then I regain control of the break. After having my brake fluid changed the brake progressively gets worse l and isn’t as strong but now it’s not too bad, until today where this thing happened again. Used the brakes after as hard as I could down a hill and they were completely fine.
I’m worried about how this happens randomly and don’t feel safe. Every time I ask the garage they say the brakes are fine and can only diagnose if they can make it happen but they can’t because it happens randomly. What do I do?
Thanks in advance for any help.
