Hey, i was just wondering how long do HP+ pads last since they are suppose to dust alot. The common concensus seem to be that they are the best pads for the lt1 brakes.

Also, can anyone recommend a good brake fluid that resist heat, doesn't expand, and doesn't absord water that much. I don't want to change my fluid more than once a year.

 

Mine are holding up well to daily use/autocross use. I'm not happy with the performance of them (but I replaced full race Carbotechs with them and reused my front rotors....a "no-no"). As for dust, the Carbotechs have turned my wheels a nice shade of "brake dust" and it seems to be there for good.

 

I got about 25 autocross events, three track events and some street driving out of a set of LS1 HP+'s. Their only weakness was that they are not really suited for tracking - they give up when they get hot. Other than that, I was very happy with the HP+'s. They were on the car when I sold it in October.

As far as brake fluid is concerned, I have not found any fluid better than Castrol SRF. It has an extremely high wet boiling point (higher than most fluid's dry boiling point). The only downside is that it is $70 a liter. In January, I will be buying 2 or 3 liters for my car. I plan on a thorough flush and then run the fluid until it gives up. ...just to see how long it will really last.

 

I use Valvoline Syntec (or whatever it's called) fluid, it seems to be the best for the money.

I love my HP+ pads, they do dust terribly and squeal but damn, do they stop.

 

I bit the bullet and changed over to SRF.

Close to 2 years ago, I bought 2 litres, used the first can sparingly. I evacuated the MC reservoir as low as I dared, refilled to minimize contamination of the SRF and bled the system. I used just a little over 1 litre.

When I swapped my brakes from C5 conversion to the PSM kit almost a year ago, I used about 1/2 litre, leaving me just under 1/2 litre.

In September, after 5 track days this years, I did a sanity bleed and the fluid was absolutely clear coming out of the caliper. I finished off the can and oredered another, just to have on the shelf.

I'm sold on this stuff ...

www.hrpworld.com has it for $60/litre.

 

Most of the time we use Motul RBF 600 for tracked cars. For some track, mostly everything else we use ATE (Blue or Type 200, same but for color). $11.95 a liter, 536 dry boiling pt., 392 wet, exceeds DOT 4 specs for it's ability to absorb moisture..... Pretty good deal all told. Motul is about the same $11.95 or so, but in pint bottles, not liters. FWIW. I've got some customers who use SRF. Awesome stuff, most don't want to pay for it.

 

I like Ford fluid. It's really cheap too.

 

ive got HP+ pads on the front. they work great. i didnt have any fading problems running the dragon three times. they do squeal and dust terribly but im used to it for the most part. i daily drive the car so they get used. i havent had them on very long so i couldnt say how long they last.

for fluid im using valvoline synthetic. its cheap, good ,and can be found everywhere. thats why i went with it.

 

Hey, thanks for your help guys. So how long do the pads themselves last before I have to change the pads. Also, if they squeal all the time, how do you tell you've used them up.

 

You don’t have to put up with the squeal. It has been theorized that it comes from excess buildup of pad material on the rotors (anything that causes or permits vibration is a culprit; the noise is high frequency vibration). When mine start squealing, I find an area where I can make 2 or 3 “anchors out” stops from 80 mph, and that cleans them. It gradually comes back over the next month or so, or if I have to drive to Atlanta and get caught in stop-and-go traffic. One hour in stop-and-go will get them squealing. I have gone months at a time without any squealing when I am driving “aggressively”.

Driving aggressively on our winding mountain roads is the most fun I have in my car off of the race course, and keeps me squeal free. But, when driving like that, I have to wash the front wheels VERY, VERY frequently.

I have the C5 HP+ pads and so far have been excellent. The only track I have used them on is not harsh on the brakes and from what I have heard they don't work well when very hot.

So for the more brake intensive tracks I think I am going to go with Carbotech's.

I also use the FORD HD fluid and have been for a few years now with great success and it is very cheap. It is not as good as Catrol SRF, but a whole lot cheaper.

 

SRF is definitely more expensive to purchase. But it sure does last a LOT longer and doesn't require the same maintenance.

 

I use ATE superblue/type 200. $9.99 a liter at OG racing and I usually buy mine at Summit Point Raceway when I'm there for the 12 hrs (and, my mother in law works there part time). I've got 7 liters in the garage right now.

I'm going back to Carbotech pads after these HP+'s. Just my preference (I seem to like noise, dust and rotor wear).

 

I think Castrol recommends replacing SRF every year to 18 months at most.

I don't know if that's because of moisture absorbtion or minimal corrosion inhibitors or what. Mine has been in about nine months, so I'll find out what it looks like sometime this winter.

 

I don't know if you LT1 guys have super
clean pads stock but my stock pads dusted equal
if not worse than the Hawks.
I think they get a bad rap in that dept.
