I did my sisters car this weekend (15 year old brake fluid, and I don't think it's been bled since then). I replaced all 4 corners pads rotors and fluid using a one man bleeder and now her initial brake bite is better than my G's . Time to do the G I guess!

 

Nice. What kind of car is it?

 

So I thought I would throw out what happened to me. Did all four brakes with in a 1.5 month period due to lack of free time and the holidays. Anyway, just got to the last brake pad (Front-right) done last week, and felt great. BUT, I thought something wasn't right when I go up to 60+mph for the first time during a drive. Some shaking, like a really bad wheel bearing, but it would go away after 30sec to 1 min. WELL.......Today after coming home from church, a 30 min drive, everything was great, until I left about 2hrs later. Started to get some MAJOR bump bump bump at 40+ mph (Almost like wheel hop), started smelling disintegrating brake pad. Summing up what I found was that my rear-right caliper was frozen, clamped down with my new oem pads.

Rotor most likely got to 700-900 oF , but no harm was done to the car. Canceled my evening plans an went to work.

*NOTE FOR EVERYONE DOING A BRAKE JOB* Keep your old brakes! I can now go to work tomorrow (My first day ironically enough) because I keep my old pads, and even though they are worn down, I can still use my car (being a one car owner) by putting them on.

I will be buying a RockAuto rear-right caliper next. And pray that I don't have to touch the other side.

 

I clean and regrease slide pins before the winter season in November, and after winter in March. G35s can't keep the crap out of the slides, wearing pads extra fast. Good luck, and use a large amount of grease.

 

So i did use copious amounts of grease, when I put on the old pads, but in retrospect, I probably didn't help my self too much (as it would probably make my problem worse). I went for a test drive just to justify driving the G to work (~45 miles) NOPE, after about 3 miles....thump thump thump, rotor was back to ~700oF, so I said, forget it, I am getting rental car for the next few days, no need to risk a job or my life while I wait for car parts.

My thoughts are as such, the hot driving caused the brake fluid to flow in the frozen cylinder, unfreezing it (temporally) and when I press the brakes....CLAMP! Same problem all over again.

 

Have you rebuilt the calipers recently? Have any of the pistons failed because of carbon deposit build up on the piston outer edge? Sounds like the pistons are not returning, and therefore wearing out the pads extremely quickly.

 

I realize this is an old thread, but just to add some more experiences. My right rear slide pins were slightly bent. Had the same wear pattern as the OP. Replaced the pins and haven't had a problem since. Also, the right rear caliper is the one that's "triggered" first when your VDC kicks in, so that one essentially gets used the most sometimes.

 

This is a great idea, except I have no clue where to begin. Recall, my piston is frozen unless it gets really hot, and I've already burn one of my fingers on brake components these week LOL.

Urbanengineer, what do you suggest?

 

LoSt180, how did your slide pins get bent? Also, I didn't know that about the VDC, thanks for sharing

 

Inspect the slide pins as he had indicated.

 

I had a few things going on, so not sure the cause. I had a bad wheel bearing that I suspect super heated the whole hub area. The slide pins were dry, and that rubber anti-rattle nipple thing on the end of the pin was deteriorated causing the pin to be stuck. I started using a silicone grease for the pins. It's supposed to be safer for rubber, and has better water resistance. I used to just grab one of those 99 cent packets at the parts store counter.

 

My front right brake caliper rubber boot came off after this brake pad level check. Had to grease like crazy.

 

Rear calipers seem to have gone down in price. Last time I did a brake job, I just bought two new calipers. Preloaded the calipers before hand, and it was the quickest brake job ever.

BTW, motive power bleeder really does make it easy to do a 1 man brake bleed.

 

But I don't want to spend the money on one .

 

Cheap azz ****. Do eeetttttt!
