Squealing brake!!! Scored front brake rotors

[sky_active]

My front brakes have been squealing in my daily driving since I bought the car 06 mz3 HB. I was told by the garage guys that the previous owner didn't replace the front rotors last time when installing the new pads. The scored front rotors are the reason for the squealing sound. Since the pads still have like 50% left, its kind of wasting money to replace a new set of rotors and pads, so I keep using them. However, the squealing sound is pretty loud sometimes and I found my steer wheel shakes a bit when brake at a high speed. Is it better for me to replace the scored ones and try not to take any risk for the safety side?

Thanks in advance for any inputs guys!!!

The squeal might be easy to deal with, applying anti-squeal to the back of the pads...the condition of the rotors probably doesn't help the matter. The shake while braking is because the rotors are warped.

If it were me, I'd replace both pads and rotors...but it's not like your brakes will just fail because of it (assuming everything is within useful limits and not worn through/out).

Replace the rotors and pads. Just get the OEM parts at an affiliate TM3 dealer for the best discount. Then install yourself, Jimmy (if close) or your local garage. You don't cut corners with brakes and safety. If you want to save money do it with cheaper toilet paper!

You know the rotors are bad (shaking), so replace them. For the small cost of a new set of pads, it isn't worth the hassle to change them out later (or cost if paying a shop). Just do it all at once. Its the most important thing on the car, and it's really not expensive to fix. :)

Since there is a lot of life left on the pads and probably rotors, you could probably take it to a garage and get them to resurface them for you. In theory should cost a lot less than buying all new parts. /Disclaimer - i've heard of people doing this but have never done it myself

Rotors are so cheap these days, not many place turn them, and the ones that do, often cost almost what a new set would.

I hope I was living in ON, but unfortunately I'm in Nl and the dealership sucks here.

It just makes more sense to me to get a new one if its necessary to get them all replaced. :(

I've had rotors machined before. Nothing wrong with doing so.
Mind you machining your rotors is never meant to be a permanent fix. If you're on a budget and the wear on the rotors allow you to do so, get them machined if you're tight on cash. If you have the funds, replace rotors and pads.

What do the inside pads look like? Sticking sliders can cause uneven pad wear.... it's very possible the inside pads are shot and you have metal on metal contact.

And don't but the cheapest crap either, otherwise you'll be replacing it again in a year. Go with the OEM parts and be done with it. Don't waste your time and money turning rotors.

Nl as in Newfoundland?

yeah, that's correct...:D I think I'll probably hit the dealer to get the parts and then maybe get them installed in other garage. The labour here is $110/ hour... :bang

I meant to say the labour for the dealership...

I can't see the inside pads coz in that way I have to take off the wheels... but i think they are basically the same and that's what the garage guy told before when I first bought her. Thx for asking :)

I'm not really on a budget but since I will only keep her for another half year, so it just becomes a question for me whether its worth to replace them. Resurfacing is not a good option for me here as no garage would like to do that by now. they'd rather persuade you to buy a new cheap rotor. Changing the front brake rotors and pads (aftermarket parts) could cost me around $350 at an independent garage.:bang

If you are mechanically inclines at all, its a pretty straight forward job.

Resurfacing the pads is extremely easy IIRC..
