New Front Pads & Rotors

Recommended Posts

Sometimes a small dab of moly grease on shims and pins helps.

I just removed my (approx 3000-4000km old) Winmax W1 (front) and W2 (rear) pads due to constant loud and frustrating high pitch squealing when slowing down using light (normal) braking pressure. The squeal tends to come and go but my god it drives me insane. I have tried basically everything to shut these pads up (swapped sides / cleaned and regreased shims / running some sandpaper over them / grinded a chamfer into the front pads etc (as they didnt have one etc etc) but nothing worked. The pads were bedded in when first fitted and I have even tried re-bedding them in several more times to try and stop the noise to no avail.


FYI when I fitted the Winmax pads I also fitted brand new DBA X Gold (slotted and cross drilled) rotors.


Was going to try either Hawk Ceramic or Project Mu NS400 but came across these Bremtec Euroline ceramic pads which looked promising and were considerably cheaper than both the Hawk or Project Mu so have decided to try these http://bremtec.com.au/product-range/brake-pads/ (I got the Euroline version which have the yellow box). These pads are chamfered (Winmax were not) and also include new shims (Winmax did not) so lets see how they go. I will update in about a months time after I have put some km’s on them.

Has anyone had any experience with RDA brake rotors? I have a set of dimpled/slotted front rotors and ceramic pads that I’ll consider fitting at some point.

RDA disks will be perfectly fine for a street driven ISF - so if they fit your budget go for them.

Just an update after a good 6 weeks or so with these Bremtec pads fitted. Absolutely no noise/squeaks what so ever which i am very happy about. I think they emit a bit more dust than my previously Winmax W1 pads but nothing worth complaining about as both are better than the factory pads which were super dusty. No noticeable difference what so ever in street driving so im a happy chappy - i wish i had bought these initially as they are working well and were very well priced.

I’ve had RR Racing 2 piece front rotors fitted, & Project Mu RC 09 pads all round.   Looking forward to testing them at the track next week.  Took a couple of pictures with the mobile phone on the way home.

Fronts were $121 incl postage

Rears were $74 incl postage

Bremtec Euroline Pads (search for Bremtec Lexus ISF on ebay and you will find them)

Overall very happy with them, they are noise-free, and for the price i was surprised how nicely they were packaged and included shims etc.

Hi John,

Those two piece rotors look awesome!

I imagine you will be able to more consecutive laps before requiring a cool down lap ... which in turn will yield more hot laps per session!

I also expect the notably lower rotor temps will extend pad time as well!

Great choice of tyre in the Michelin Cup 2’s for the track!

Have fun this week and look forward to hearing how these new two piece rotors go.

PS: Your car looks immaculate as always!

Regards, 

Matthew

The RR 2 piece rotors were excellent and didn’t fade in each run on the track.   to me they felt about the same as the Lexus rotors with the same track pads, but the RR 2 piece rotors have better cooling, & will take longer to fade.

I knew my front tyres were getting low, but I thought they would last the day.  sadly after the first run after lunch, I was checking the tyre pressures, (46psi hot) & I had worn through to the belts.  It’s time for new front track tyres.

Hi John,

My god! You have almost driven the tyres off the wheels!

I actually had a Michelin Pilot Super Sport 3 do that too me as well ... so completely different tyre, but exactly the same outcome with the rubber on the tyre literally being peeled off the outer edge and all being deposited into the centre of the tyre ... I also had worn it down to the cords / belts before I noticed too!

I also always run 40 to 44psi ... and the day this happened the track wasn’t that hot, so in my case I didn’t think it was due to overheating tyres but a soft sidewall ... since moving to a ‘street’ semi-slick (200 UTQG) though and their stiffer sidewall I haven’t encountered that problem ... and I have given it a really good go!

I think the AD08R’s have a stiffer sidewall than the Cup 2’s ... same UTQG rating of 180 ... or you could make the move to R Comp tyres and further capitalise on some of those mods you have ... I am pretty sure you would find the Toyo R888R & Nitto 01’s (100 UTQG) are less expensive than the Cup 2’s ... and as you know you can still drive them to and from the track ... but they will probably last only half as long on the track ... I have just changed over to the Nitto 01’s and are looking forward to taking them to SMSP ASAP! ... There are of course stickier R Comps out there like the Yoko A050 (in varying R compounds) but they are notably more expensive too.

If you interested I thought this Track Tyre review was pretty good ... it doesn’t have the Cup 2’s in it though;

http://trackdays.ie/track-day-tyres/

Coincidentally I was actually at Lexus Service today, as I just changing over my track pads and realised I had lost my lock nut! Chris helped me out with their ‘master set’ and I fitted a new set of lock nuts. I asked how it went yesterday and whether you were there ... he mentioned that it dried up by about mid-morning and that you had completely used up your Cup 2’s!

Trust you had a great day and glad to hear the new two piece rotors went really well. I am sure you will notice your brake pad life will also be notably extended with the lower rotors temps.

Regards,

Matthew
