Brake Pad Change (Front Only)
#61
can anyone explain to me how the brake system works? I have been wondering this since no one was able to give me a direct answer but only assumptions. Do both the front and back brakes lock on when you stop or somewhere along the lines of 60/40. For example the front brakes lock first, then the back brakes come on afterward. I always thought the front brakes were the only brakes that worked but recently I have been seeing plenty of owners swapping out their rear pads. On top of that, I know that AWD cars use the 60/40 ratio but is it the same for our car?

Not necessarily. You'd have to use your judgement on that I think. If you notice a lot of pitting or grooving - you might want to. If they seem pretty smooth overall - skip it. Just be sure to follow proper bed-in instructions for your pads.

Anyone know the actual method?

The manufacturer's actually have varying recommendations on this. Here is a list of the most common names and their procedures:

One of the key things here is that you do NOT come to a COMPLETE stop while bedding these in. Generally it is a few hard braking stints from 50-5mph or 60-10 or something like that. But definitely read through those above and you'll get a good idea.

if your getting noise it's from lack of brake paste or using old clips/backing plate. that autozone brake paste is crap..
also, you ahould perform a brake fluid service every 2yrs. brake fluid is extremly hydroscopic.
another thing,, we have floating calipers, lube the guide pins.
another thing, don't not open the bleeder to do a pad/rotor service, usless you have a PRESSURIZED bleeder hooked up or plan on doing a brake fluid service. you will get air in the lines,,, (remember we are surrounded by 14:7psi of air pressure) the abs pump will by fine.

With floating calipers, it is important to (clean, replace or) at least grease both pins. It is ill advised to touch the rotor with your bare hands, because any grease/oils can create stopping issues. Lastly, most good brake kits come with new backing plates, and anti-squeak; which is not grease. I have had best results from the spray on stuff, to quiet noise; and wiping up dust helps, too.
Re. what Domo said about f/r balance- Brakes have a check valve that typically varies the amount of pressure/force applied between front and rear. Not sure 100% if this is true for tC 'cause they actually have separate master cylinders. A manually adjustable system is often installed/used by racers.
As mentioned, it is a good idea to remove some brake fluid from the resevoir before pressing the piston, due to its very corrosive nature to paint. Brakes can gather water (and dust) over time, and it's a good idea to bleed/replace fluid; to get out any dirt, air or water. Kits are easy to find (even make). Make sure your at the right level before you call it a day.
A ghetto way of changing much of the fluid is to use a syringe/baster to pull out as much as possible from the resevoir, but not all the way so as to introduce air in. It's important to not touch the pedal during this and dispose of used fluid with a recycling facility! You can't expect to get it all clean, you get what you pay for.
ReticulatingPigeon- driving with the e-brake won't ruin your rears. the e-brake is an inner drum-style, that's separate from the disc setup. Your e-brake may be worn tho'

Anyone have a picture of the guide pins? and what type of grease.
I replaced the pads already. I should have read all the post before I put everything back together.
It was easy enough with this tutorial that I want to take it apart to grease the pins.
Thanks for the help. Saved me $$.

Reviving an old thread...
I am going to change front pads/rotors on a friend's '06 tC next weekend. The car sees 100% casual street driving so there is no desire to put high performance parts on the car. The pads will come from Autozone or OEM from trdsparks.com.
My question is about rotors...where do you guys usually buy them? Right now it is likely that I will get them from Autozone or NAPA. Are there any potential issues with rotors from these stores? Should I stick with OEM for the rotors?
