question about changing roters

Postby Tagged » Sun Dec 05, 2010 12:42 pm

Hi all,

I got my brakes checked by Magoose and found out all four roters were under and needs changing.

Got a quote for 1k including roter change, full brake servicing and new pads.

I thought I'll just do it myself when I get the cash since it aint suppose to be hard...

So is there anything in particular that I will need to pay attention to when changing roters?


Also I asked the mechanic about the knocking noise at the back when having a full load, he told me its is highly possible that bcoz the struts are original and lowered on shorter springs, the struts are bottoming out from the inside, which is making the knocking sound, what do you guys think about this? and if you agree, wats the solution to it?

Thanks~~~

Changing rotors is ridiculously easy man, takes an extra minute a corner when doing the pads. Get them cheap through our sponsor, cheap pads and you're away laughing. Full brake servicing = bleeding brakes, not too difficult either.

+1, Only thing i would say is can one of the experts advise the process for ensuring good bedding in of pads and discs?

I did on a couple of cars and it was piss easy but a little while later i got a bit of a shimmy under light braking, hoping someone can advise what was wrong so this chap (and myself) will know what to look out for :D

If brand new brakes are squealing, if you put some antiseize grease between pad backing plate on the pad and pad itself ( normally it goes like this: piston, plate and pad) the squeal will stop.

yea i had a look over YouTube and all you need to do is unscrew screws and removed old stuff, put the new stuff on and put the screws back on.

whats bleeding brakes though? heard of it b4 and thought it means to have leaking brake fluids @@"

It's a piece of piss job to do. I don't mean to offend you though but if you don't know what brake bleeding is then perhaps get it done by a professional - there are plenty of mechanics on Toyspeed that will do a perky for ya for cheap. I'm all for DIY and saving money but brakes aren't really an area you want to be playing around with if you don't know what you're doing IMO.

Last set I did, I just popped out to the 100km/h zone and did a few scenerio's of braking :lol: Nothing too hardout, nothing clinical about what I did either, but shit they work pretty well so can't be too far wrong. I guess different pads will have different methods though. I was just dealing with cheapy pads, easy peasy.

Doing brakes is really easy, IF you know what you're doing. If you don't, there are many things that can trip you up first time. Bleeding the brakes is probably the most important part of the job too.

Bleeding brakes is just replacing the old fluid in the lines with new stuff. Brake fluid is fairly hydroscopic, meaning it absorbs water over time, so its' a good idea to replace it every couple of years, or when its' dark and murky.

Has your car got ABS? If so, you need to be more careful with keeping the reservoir topped up as you bleed, as if you get any air in the ABS unit it can be very hard to get it all out again!

Why do you think the disks should be replaced?
If they don't need to be cut down because of runout causing the pedal to pulse, just leave them alone. There are way too many replaced just to run up the bill. Sure the new pads will need to bed in to conform to the old disks, but that's a small price compared to disk replacement.
It needs pads, it needs its caliper slides to move freely and that's about it, and if you don't have any experience at all, read everything you can & Utube before hand.

the discs may not need replacing, magoo's and other places like that quite often tell you to replace them just to get more work/money out of you

id say get them checked somewhere else first as it mgiht save you some money


also bleeding brakes is getting all of the air out of the brake lines, if theres air in the lines you'll have almost no braking power

i didnt think that youtube video was great, id look for some different oens before you start
The four seasons in Australia consist of "$&#$% it's hot", "Can you believe how $&#$% hot it is?", "I won't be in today because it is too $&#$% hot" and "Yes, the dinner plate size spiders come inside to escape from the heat."

take the wheel of and measure the discs and see if theyre in spec. If theyre not warped etc... you would only replace them if theyre thin.

I guess it depends. Last 2 brake services (2 ae111s) I did included new discs, pads and fluid. I'd rather do it once and know it's sweet for a couple years than fart around down the track with possibly having problems with discs getting thin / warping.

Sure it costs more than just doing pads, but I reckon do it once do it right if you're keeping the car. I've gone through our Toyota sponsor and also through Dell'orto for brake parts both times it was half or less than your quote, for discs, pads and fluid.

Time wise it takes the same amount of effort to do it all or just pads/fluid.

my 2c

As for the rocket science call, you're right it's not. But brake companies aren't charities and have staff / leases to pay for so of course they won't do it for cost price... I wouldn't turn up to your work, tell you what you do is piss easy and that you shouldn't get paid so much :wink: (hypothetical situation)

haha yea i think you are right, almost half of that 1k is labour i think....which is the most expensive part most of the times regardless of wat you want to get done....@@"
