Where you buying these? I've been looking for something like this and haven't found a "reasonable" source. I don't mean cheap but one clown quoted me $75 per hose.BDiefAZ wrote:The best brake upgrade I have done is the SS braided teflon hoses to replace the 5 stock hoses.
WTF are you doing on a regular basis. Something is truly amiss here. I have never heard of rear pads going out first. I thought it was a universal rule like fuel is lighter than water. The front pads are doing the majority of the braking. Do you have any ABS related codes? The least amount of miles I ever got out of front pads was 4K and that was on a law enforcement packaged Tahoe and the conditions were extreme.roadrunner wrote:.................. If I get 20k out of the fronts and 8-10k out of the rears that's about it. I have gotten as little as 2k out of a set of rears and they were clear down to the metal on all 4 rear pads.............
No codes. Other than that pesky "low no pedal" problem in another post on rough or rutted roads no other problems either.f9k9 wrote:WTF are you doing on a regular basis.

Tried the ceramic from NAPA and GM and Two other sources all =1/3-1/2 the life of the metallics so, No to that one.HenryJ wrote:I would get away from the semi metallic and go back to ceramic pads.
I run a fleet in worse conditions than you can imagine. The ceramic pads do better in the offroad conditions than others. Try the NAPA brand CMX pads.
I would not drill the calipers for grease zerks, nor the pins. Weakening them is not a good idea. The next issue is that you would need to find silicone brake lubricant in a tube for a grease gun. It may exist, but I have not seen it.
Lube the pins. Use good boots and replace them if needed. Contaminants should not enter in your 20k intervals.
I am with Reed here. Something is not right, somewhere. If you are truly having problems this bad with your crewcab, I would sell it and find something that will give you better service. 8-10k miles is not an acceptable service life for brakes, IMO. Shop for a vehicle with better suited systems.
I am on your side so, try to keep that in mind. I am really puzzled by this. Something else is involved here. Let's just sleep on this issue and maybe you can do some sort of write up on the problem. There is a former GM engineer on USAZR2.com and there are many other gurus out there, that may be able to help. Your problem is just wrong on so many levels. I bet if, you write it all out for us that Brule or Steve will come up with valid solutions to try.roadrunner wrote:............. That's the main reason I keep so many brake parts on hand for the truck.
I am probably older than you but, either a PM or here is good.roadrunner wrote:You want it on forum or as pm? Let me know which and I'll post it tomorrow afternoon. Gettin late on me here and I gotta get up at 6am tomorrow. Old geezers like me need some rest from time to time.
Will try tomorrow. Spent all afternoon and evening till 10pm wrenching on car and pickup tonight. Not for fun just emergency repairs.f9k9 wrote:I am probably older than you but, either a PM or here is good.
I've been considering either mud flaps in odd places or possibly scraper/deflectors ahead of the calipers but haven't settled on locations or designs yet. Workin on it though.green02crew wrote:I have been told that the calipers are not in the best location as well. Sometimes the rear brakes might wear oddly due to their location but going through brakes that fast seems unreasonable to me.
I sincerely think that this is a strong possibility. I am thinking that the proportioning valving may be amiss. Jug has already posted up on ZR2 USA.com because he is having similar problems with a his BlaZeR2.HenryJ wrote:Rotors.
Still originals. Smooth & no pedal pulsation or braking unevenness.HenryJ wrote:Rotors.
From what I understand of our ABS and prop valving it is sort of a cross-connected system. If so I don't think it likely one end or the other of the truck would suffer wear excessively compared to the other especially the rear compared excessively to the front. But perhaps my understanding is incorrect. Thoughts/knowledge anyone?f9k9 wrote:I sincerely think that this is a strong possibility.

Definitely a new train of thought for me to try to understand. If, this works I have a very large piece of humble pie to eat.HenryJ wrote:ZR2 USA thread
Big waste of money. The braking performance is poor on a daily driver. Stick with the stock rotors.Rockrz wrote:Anybody using slotted and drilled rotors?
I've heard these help keep the pads cooler and cleaner, or so they say.
I think my problems stem from only using the CC when the roads demand it (mud). Otherwise when it's dry it mainly sits in the front yard. My route is about 6 miles paved and 100 miles mix of dirt and sanded dirt. Hence the diagnosis in the post above by the brake folks. Also as stated before I have tried all the different types of friction material out there to be had with no better results.JaVeRo wrote:My wife runs a mail route with her crew cab and gets about equal wear for the front and rear brakes. About 45-50 miles is dirt road. I really think part of your problem may be the proportioning valve.
If you have access to an infrared thermometer (or whatever that doodad is called) you may be able to check the difference in temperature of the front and rear rotors while you are on the route. No experience with it but just common sense would say they should be about the same.

Obviously an old thread, but I would lean towards a ABS valve. Even with the ABS fuse your fluid is still routed through the ABS valve assembly which divides the two lines that go into it, one for the front and one for the rear, into 3 lines going out. One to the rear and one to each front wheel. On another note, my 2002 cc has the calipers on the rear axle are facing the rear of the vehicle. Now on another note, I've got an 02 2wd blazer and the calipers are facing the front like yours are. I also have an '01 4wd blazer that I will have to look at the rear axle to see which way they are facing when I get home. I think it's weird that GM did not make all the calipers facing the same direction on the rear axle across the s-platform since it is using the same axle 7 5/8th, exept on the zr2 which uses the 8 1/2. Even when you look up calipers on autoparts websites it will give you which side they think it goes on, then it says may be used on opposite side of vehicle.Tried the ceramic from NAPA and GM and Two other sources all =1/3-1/2 the life of the metallics so, No to that one.
Not drilling calipers or pins, just the mounting bracket they hook onto. Not going to be large holes either. only 1/8" or less dia except where zerk is installed. The silicone grease and gun are no problem. I have a "reloadable gun, just a matter of what I load it with.
All things are relative. I can imagine some extremely bad conditions and have driven in some as well. You know you're in trouble when you have to go to Lo4 and Lo gear and run red-line for 1/2-3/4 miles moving at only actual ground speed of 4mph or less to get your a** out of a jam.
I've replaced the pin boots more times than I can remember and no they won't make it 20k for me here. Not on the rear for sure and not always on the front either.
I've considered the replace the vehicle route as well. One problem FINANCES dictate I am unable to for at least three years yet and my job requires I use the CC when weather is too bad for any other vehicle.
I have discussed this problem with other "wheelers" in the area and the general consensus is that the main reason the S10 rears go out so often for me is the placement of the caliper on the front side of the axle instead of the rear side like other brands. This leads to the wheel "dumping" contaminates on the caliper instead of forward of it. Don't know if this is true but others with calipers mounted on the back side of the rear axle are not having the type trouble I am so who knows. I am unaware of any way to move them to the rear of the axle without considerable welding/machine work either.
