Q: Brake fluid was recently bled/flushed and the brakes still feel like they are grinding
What should I look for now? My brake pads are good. I had those looked at a few weeks ago and I was told that they look like they are new. But when I come to a stop it feels as if something is grinding. Also I feel like they are not as "strong" as they need to be. As if they are spongy, if you will and when I test them every now and again and I try come to a sudden stop, its like it takes a while to come to a full stop instead of stopping abruptly like normal cars. I thought servicing the brake fluid would fix this and it has helped a tiny bit but I want the problem GONE. I've been researching online and I thought maybe to replace the Master Cylinder? Or maybe to completely replace all my brake lines and hoses and such? Or is it another part in the brake system that I should consider? I just want my brakes to feel normal once and for all. Could it maybe be a leak? I remember seeing large spots on the ground behind a few tires after its been sitting a while.

Good question and thank you for the details. I want going to go through some things you may want to check and hopefully save you some money. If you come across a problem in any of the areas you will need to fix the problem but do not stop there. Continue checking everywhere else to ensure all problems are fixed.
- While the car is off pump the brakes until they are tight.
- Check the master cylinder to ensure it is full. If not, fill it.
- You may need to re-bleed your brakes. Sounds like there still may be a little air in the lines.
- Check your brake lines and see if you have a leak somewhere. I would start around the wheel well areas. My reason for this is because a lot of people will let the caliper hang instead of tying it up like they should. When I explain it as a leak, any wetness on the lines is a leak and dangerous for you to drive.
- Check to see if your master cylinder or your hydro-boost are wet.
- I know you were told that they look new but you need to see for yourself. Check for rust on your rotors though because this is a problem you may see if you live in an area where the use salt on the roads.
Note: if you have a bad power steering pump, your brakes may be affected by the bad power steering pump. The hydro-boost (hydraulic boost) connect the brakes and power steering. To know if you have a bad power steering you will hear a grinding sound under your hood while steering.
