Replying to: axiomguy (Aug 18, 2006 9:27 am) The first thing to say about drums is that periodically you need to pull off the drum and dump out (in a bag for proper disposal) the accumulated brake dust. Otherwise your pads are just gliding on the powder and won't stop well particularly if water gets inside during rain and snow. With discs years ago we used to take a coarse grit piece of sandpaper and scuff up the rotors. Then with a very clean rag we would wipe off the filings and residual grit. It wasn't as pretty as latheing the rotors, but you did not have to replace too thinned out rotors every few years. Roughing up the surface would get rid of the glaze and oxide of stop and go driving, and I wonder if you could do the same to the inside of your drums. I think a lot of the vibration and moaning is a combination of glazed rotors/drums and pads, and the oem pads have a very high affinity for moisture retention even in just humid weather. Thanks for the parts referral. I should have made my question more specific. I mean't to ask is anyone having trouble getting repair parts like master cylinders, alternators, body parts, etc. I've seen some posts where people say they have to wait a month or more for replacement transmissions. If I were in that circumstance, I would prefer to have the original tranny rebuilt by a tranny shop. At least you know what your starting off with. But maybe those folks were not even offered that as an option. I was also wondering about access to maintenance parts like oem filters, gaskets, etc. Thanks for any info you can share.

Replying to: axiomguy (Aug 23, 2006 8:54 am) I know some of the axiom problems are a nuisance and frustrating, but if a person were to look at some of the other SUV's in this website, they'd see we're all doing pretty well considering everything. My concern was availability because of Isuzu's semi-comatose non-commercial vehicle status, but your post has helped to allay some of my concern. Thanks, it is appreciated. |

On 2 different occasions prior to today, I've taken my 04 axiom to the dealership svc. dept. where they couldn't "duplicate my concern". Today (finally) my car decided to act up while I was at the shop. I was told by the technician "This is a common problem with most Axioms & Rodeos & we see this often". I asked if this was covered under warranty if this is a common issue and he advised it wasn't because it isn't a safety issue according to Isuzu. After several hours at the shop, I was told that Wagner R/Shoes (and only Wagner shoes) & resurfaced drums would solve the problem. I'm not Car Savvy so I called my father and he's told me that a car that is fairly new with less than 30,000 miles, the R/shoes should be replaced AFTER the F/pads. He feels that it is a manufacturer defect and that Isuzu should fix this since it is potentially a safety hazard. Any opinions on this? |

I happened upon this site by accident and decided to register so I could let you know exactly what the problem is concerning your pulsating brakes. For those of you who just want the facts and do want to read about my experience here it is. Your rotors are warped and need to be replaced. Cutting or resurfacing the rotors will help alleviate the problem for a little while but will not get rid of the problem. I brought my Axiom brand new in the summer of 2002. I had front brake problems after about 15,000 miles. The ABS sensor lights went bad twice and had to be replaced. I also experienced the squealing sound as well. I had the front pads replaced and the rotors turned twice. In 2005 at 49,000 miles was when it was last done. A week after it was done I went back to the dealership and told them that the work they had just performed had not solved the problem. They told me, "Well we've done everything we can. What else do you want us to do?" The problem never went away and I just dealt with it. Today I took my car into a different Isuzu authorized service center to have my brakes replaced. I told them the problem I was having when coming to a slow stop. They resurfaced my rotors and replaced the pads again. They told me that if I wanted to completely get rid of the problem what I needed to do was replace the rotors because they were warped and had hot spots. They said this was the only way to get rid of the problem period! Upon having my service record pulled from the dealership who did the last warranty work back in 2005, I noticed that the tech who worked on my car stated my rotors were warped back then but they never made mention of this fact. Isuzu knows there is a problem with the rotors on these Axioms and they are just praying owners like you and myself will just go away. They really don't care and don't want to make it right. |

I respectfully disagree with rchaynes posting #18, and this problem is much more difficult to resolve than simply resurfacing rotors, or replacing rotors (which I have also done myself personally), or adjusting the, or replacing brake pads. I have done all of those tasks more than once and still have recurrences of the noise problem. I have posted this and more under the maintenance section, but will repost again here for the benefit of those with brake problems: ************************* From June 9, 2009: As my prior postings have detailed, I have struggled for a couple of years now, or the last 50,000 miles, whichever you like, with noisy brake problems and rotor problems. I solved half of the problem last summer, when my friend and I replaced the original OEM rotors (which had warped for the 2nd time) with some drilled and slotted high temp rotors that I bought from SummitRacing.com to fit my vehicle. That cured any issue with rotors getting too hot and warping. However, it did not get rid of the squalling noise that the brakes make, especially when you first apply the brakes the first time, or on any downhill braking situation, and at other times at random. So, tired of the problem, I took it back to a good mechanic, who took the front and rear brakes apart, cleaned them, readjusted the rear brakes and lubbed the backing plate for the brake shoes (which oddly at 94000 miles did not need replacing yet), and then deglazed the front pads (which are only about 8 months old). They also used some special product made by B& J that reduces pad noise. (I do not have the name of the product). I can say that the past few days have been wonderful. No more brake noise. I suspect that the problem all along was that the rear brakes were not doing what they should have been and the front brakes were doing most of the work, which led to excessive heat, rotor warping and pulsation, noise and glazed front pads. I would also speculate that since this is a somewhat heavy vehicle (4700 lbs) that others are having the same problem and do not know what it takes to get it fixed. The racing rotors were a big help, but ultimately a cleaning and adjustment was also needed to fully resolve the problem. Hope that helps. ************************* From June 30th: I spoke too soon. The problem has come back again 2 weeks later, at least in part. The brakes still squall (I think that is the right descriptor) when you first apply them, until the rotors get wiped clean. After that, they can squall again under certain circumstances. While the cleaning and adjusting helped a great deal, the problem is anything but gone. Someone suggested that I rebuild the calipers. I bought the parts; have the instructions; it looks easy enough, but I am squeamish about doing it. Anyone else noticing this annoying problem? Any ideas? ********************************************************* Keep in mind that I have brake pads that are less than a year old and racing rotors that are high temp, drilled and slotted from SummitRacing.com and are not warped!

Replying to: walk_the_walk2 (Jul 02, 2009 6:20 pm) The Akebono pads, he told me, were a better match for the drilled and slotted (dare I say warp-proof) rotors which I bought from Summitracing.com, that I installed about 18 months ago now. The new pads are great. With only one week to go on so for, the noise problem is gone. But, the real proof will be if I can go 4 or 5 weeks without the squalling noise coming back. It seemed to be humidity related, and pad-related. Beware - the manufacture date of an 02 Axiom is critical. Mine was built in April 2002 and uses the same pads as the 03 Axiom, but not the same pads as the early 02 Axiom, which is why I got the wrong EBC pads when I ordered online. Here is a picture of the Akebono Proact pads I am using. Expensive ($70/set) but well worth it. They are low dust, low noise ceramic pads. Akebono Pads Brochure PDF So, if this works, the final solution set for the Axiom brakes noise problem is to get warp-proof drilled and slotted racing rotors and high quality pads like the Akebono, and replace the useless OEM parts. Also, beware of the cheap aftermarket pads and rotors. If your rotors are warped - buy new ones and replace them - don't waste money getting them resurfaced - they will simply warp again a few weeks later.">link title |

Was just at the Isuzu dealer and the service guy said there was a problem with the inner pads absorbing moisture and causing problems like high wear and rotor warping. Could be one of the issues and I bet buying premium pads is a solution. Regards Bert

Replying to: bertbcfm (Nov 21, 2009 8:14 am) So, even with the new pads, the problem was not fixed, but it is improved about 75%. My guess is that there is a common problem with the Axiom brakes, which would probably warrant a safety recall. If the brakes are getting moist, I have to wonder if there is reduced braking power during that first braking event. Still, for those who want to REDUCE this problem - drilled and slotted rotors do not warp and the premium Akebono pads I used help, and do not generate dust. |
