Hi all,

So all the brake dust my GS is throwing out is driving me crazy, and I'm pretty sure I'm not the only one. If the wheels are clean and I take the car for a spin, it only takes about 5 minutes before the wheels are covered by brake dust again. Our cars are throwing out so much brake dust and I really hate it. I searched for a solution for this, and found out that Lexus makes brake dust covers for the GS. I'm wondering why my car doesn't have this since it's an OEM part, but anyway, I'm looking to buy this part.

The question I've got now is, are these brake dust covers worth it and are they good? I think the covers are gonna solve the brake dust problem, but are the covers gonna hinder the brakes from cooling down? Will it damage the brakes in any way? It shouldn't because it's an OEM part, but still...

These are the part numbers for anyone who wants them as well:
4778130191 (Front Right)
4778230191 (Front Left)

Thanks!
Regards,
RRGS

 

Switch to Akebono ceramic pads and the problem is negligible.

 

yes, akebonos are great, very minimal dust if any at all.

 

Huh?
These are the factory dust shields that go behind the rotor. If you don't have them, you should as they are meant to be there. I think they also contribute to brake cooling, the way they are designed.

 

I don't believe I have these dust shields, Can we get some pics of what they look like?

 

 

Why doesn't he have these on his 3gs?

 

These part numbers are for the brake dust covers that behind the rotors. They protect it from debris and channel air to cool it as mentioned above. Your car already has these sitting behind the brake rotor out of sight. What you are looking for are THESE (cheesy IMO) aftermarket covers that mount between the wheel and the brake rotor and caliper. The keep the brake dust, and probably the brake heat, from exiting via the wheel spokes.

My advice: take the advice already given above and swap out your brake pads for a high quality, low brake dusting set.

 

Thank you all for your help. Ok so they are installed behind the brake disc? I was thinking they would slide over the brake disc and calipers to prevent brake dust. I don't want those ugly aftermarket covers. But anyway, those OEM covers are called brake dust covers...but they don't prevent brake dust at all or am I wrong

 

I imagine they stop brake dust from going into the engine bay and intake system. But brake dust has to go somewhere. You cannot prevent/stop it, but you can either reduce it showing up on your wheels with different friction material (pads) or those awesome covers I posted.

Full face wheels is another option.

 

It's the cheap pads you have on that's giving all the dust more than usual. When I switched to the akebonos, brake dust has been reduced greatly and car stops on a dime. It's a win/win. Keep stock oem look and parts because that's how Lexus designed them and switch your pads for better ones.

 

I don't like full face wheels Debonair, I'm really in love with my current wheels! My dad bought the GS with this wheels. But thanks a lot for your help, now I understand the brake dust covers.

Thanks for your response slaapen. I think I'm going to upgrade to those ceramic pads, how do they perform in comparison to the OEM pads? Do I need to get ceramic rotors as well? I currently have OEM rotors but they are like new.

 

Akebonos are OEM with better design and dissipates heat and the materials(dust) a lot better. I have the OEM rotors on my GS and since they were smooth, I just changed the pads and my car brakes on point. I've recently washed my car with a pressure washer and pressure washed my stock wheels and brake dust on the wheels have reduced to a minimum. Wheels still look fresher after constant braking over the past week.

 

Thank you very much! I'm going to order the front and rear ceramic brake pads.

 

Get those akebonos man, they are really good quality pads!
