Outer Limits 4x4 Board

are the front brake pads in a wt sierra different to nt sierra. if so what is different ? will nt fit in wt calipers?

Same pad dude just be careful what u use anything but bendix is shit trust me............ ask me how i know!!!

How do you know?

My sierra had lucas pads fitted to it when i bought it. I went to fraser island and after 3 or 4 brake applications slowing down for creeks the brake pedal went to the floor!!!!!! The resin in the pads release gas when they get hot, and this gets trapped between the pad and the rotor, so no matter how hard you push the pedal, the pads wont grip the rotor properly. I had to stop and let them cool down for about 15min but we almost went down a foot high creek bank at 80km/h. pretty scary! I fitted bendix pads when i got home, and have tried to make it happen agian but cant. Thats just something to remember..........

You must be joking - do you know anything about how a brake pad works, or do you just make assumptions?

One of the best brake pads on the market at present

When you go through creeks your discs and pads get wet and don't work no matter what the brand

You mean dry out

Worst pad on the market - example is the bendix advance fiasco.

You probobly haven't driven through water as deep as you did at fraser since.

I have to agree .. I ran servral different brands I also used some narrow track calipers on my wide track .. I found the bendix no better or worse than the ferodo's or lucas .. and that was using stock brake disks etc on 33's and 35 bias plys (much greater rotational mass than a radial, therefore harder to stop)

Wow no idea, you fire up pretty easy! You have obviously never cooked a set of brake pads before! You cant wet brake pads in the creeks at fraser(eli creek perhaps), as most are only a inch deep as they are realy just fresh water springs thet run out of the dunes on to the beach. As for my understanding of how a brake pad is constructed, if you can explain why the brake pedal goes to the floor when brake pads start to smoke( not steam, steam does not stink), and the brake fluid has not boiled, im all ears!

That would be called brake fade

But I thought you were an automotive mechanic?

or should i put 1st year apprentice in there somewhere?

Some links to info on brake pad "gassing". I have more info, but its in text books and i dont have a scanner. I think i just found out why you are called "NO IDEA".................. A cheap shot sure, but so is doubting my abilitys as a mechanic when you havent even met me! We had guys like you when i went to TAFE for my apprenticeship, they used to end up head first in wheely bins........

The construction of the tyre has nothing to do with its rotational mass!

I have read your links, and I am aware of the phenomenon of pad gassing,

I do not understand how this will make the pedal go to the floor ( and this dod not seem to be explained in your links either), unless you had overheated the brakes anyway. I would have thought that with pad gassing the pedal will go "wooden" and the car cease to stop, rather than to the floor.

It is generally difficult to induce brake fade in sierras, they have very very good (front) brakes.

Is it possible to get sand/surface oxidisation between pad and rotor?

Im not sure why my pedal went to the floor, it happened in another car of mine to (a kingswood) slowing down from about 180km/h a few times in a row, the pedal was still solid though, it just did not work! We were away at fraser this trip for about a week and i had the poor zook loaded up to the hilt with stuff (about 400kg), the springs only had about 15mm from the bump stop. I just thought when i posted in this topic i would share what happened, because it suprised the shit out of me, i know sierras have good brakes to! Has anyone ever boiled brake fluid and had the pedal return to solid after a while? I also realise that lucas make a decent brake pad, but in the 5 years i have been in the trade, fitting 3 to 4 sets a day, we have found bendix pads to be the best around, apart from a few dud sets when they went to non aspestos( standard to advance), they were replaced straight away, no questions asked. We only fit lucas to european cars that bendix dont cover, and they tend to dust up the wheels, and make noise to. This is only our opinon, not gospel, and everyone has a right to disagree.

I DISAGREE BIG FELLA
