grinding

alright, well i'm running srt prokits with my stock struts. i recently blew my struts coming from cali 2 weekends ago. and now i get a really irritating grinding noise from the drivers side, which sounds like my brake pads are down to bare metal. yesterday i checked them out and they look perfectly new since the last time i changed them, which must have been 4-6months ago. what is that grinding noise?

Did you look at the inner pad as well as the outer? If the caliper is sticking, the inner pad can wear down to nothing but the outer would still look new.

yeah both sides only on the drivers side is still thick like new. which means i have to replace my brake cylinders, right?

Wait, I'm confused. Are you saying that the inner and outer pads on the drivers side (where the noise is coming from) are still like new, but the passenger side inner and outer pads aren't?

Sounds almost like a seized caliper piston or caliper slides. If its the slides (The little rods that the caliper rides on), you can take them out and, if they're all rusty or dirty, you might be able to buff them clean and lube them with high temp silicone brake grease.

Now if it's the caliper piston, you need to replace the caliper.

Make sure you bleed the system thoroughly to get any old, nasty (possibly rusty as in my case in '07 when i did the master cyl in my '01 neon) fluid out of it. I did a full flush. You just bleed them the way you normally would (one person turning the bleeder and another pumping the brakes) but you keep filling the reservoir with fresh fluid and bleed until nice, shiny gold fluid comes out the bleeders. You may already know this but bleeding order goes from the corner farthest from the master cylinder to the closest or rr, lr, rf, lf. If theres crappy fluid, it can cause the proportioning valves to stick which, in turn, can result in stuck calipers or wheel cylinders. The LR wheel cylinder on mine was sticky. I replaced my master cyl due to bypassing and flushed the brake system and no more sticking wheel cylinder.

Good luck and I hope my long ass post helped somehow.
