Rear Brake Job - Sensor question

Want to do my rear brakes this weekend.

Couple of quick questions,

Do I need a new wear sensor too? It has not triggered yet, does that mean I can re-use the old one?

Also, my parking brake handle pulls quite high. I figured since I am doing the pads and rotors might as well do the brake shoes. Or is it really the cable that needs re-adjusting at the handle and on the star shaped nut in the rear?

Also, any recommendations for brakes? I got a dealer here, is OEM really necessary or if I stick with the middle class Napa stuff im good?

The brake sensors are pretty brittle, so if you are able to very carefully pry it off of the old pad then you can reuse it. You can't reuse them if they "tripped"

Ah, alright well mine hasn't tripped yet.

Guessing these sensors are only available from the dealer?

Why would your shoes be worn?

What severe duty would indicate that these are not almost new?

And rear brake sensor breaks easily, so good to have one spare if needed. Do you want to run to the store like I had to do when replacing brakes? Available from dozens of online BMW vendors. Return it if you do not use it. Tiny little spring clip easy to lose.
Rear brakes adjustable at the console handle.
All this trouble, why not get superior pads that will not dust nearly as much, but with great braking ability? Take a look at Axxis Metal Masters strongly recommended at the Turner Motorsport site. Fantastic on my car.

If you are super super careful sometimes you can reuse them. Typically they are replaced during each brake job.

With the hand brakes the cable often stretches, when you reach the maximum adjustment it's going to be time to replace the cables. There are two cables a right and left, you'll want to replace both at the same time when that time comes.

I've had my parts specialist put together RPS (Rotor, Pad, Sensor) Kits for the Front and Rear of most BMWs. Your 330xi is one they have covered. I'm not familiar with the quality of the middle of the row Napa products but the Brembo or Zimmerman rotors as well as the PBR Ceramic Brake Pads found in our RPS kits are not only direct replacements but all quality products.




If you ever have any questions or need help finding parts feel free to shoot me a PM!

I usually replace the sensor anyways since it costs about $8 for me. The brake job is very easy, just make sure you have a nice 12" breaker bar.

I see their bad, the mechanic told me inspection will be a no go until changed, the PO told me so. Very obvious their done

Just picked up all the stuff from the dealer. It was the cheapest around town than anyone else. Picked up pads, disc and sensor. And I would of ordered online but I needed them this weekend so ordering was a no go. Also I am not even sure how much I would of saved if I had ordered online after shipping/ and a chance of duties to Canada..

The word Canada convinces me

you did the right thing! If in the states you get free S&H from most everyone.

Good Luck! We're here on weekends too. Hope your rotors pop off easily.

Yah I'll be doing it with a buddy so I'll have an extra set of hands. Overall the cost wasn't too bad just the dealer wanted a tad bit too much for just the brake shoes and the spring kit ~$200.

I priced out the brake shoe kit online from a canadian retailer and the shoes and spring kit and its like 120$ cheaper. So down the road I can always swap those. For now I'll just adjust the cable to lower the amount I have to pull the handle.

I was able to reuse my brake sensors when I replaced my pads. The corners were chipped a bit when taking it out but still usable. You just gotta pry it out carefully.

Yah I will try and remove it without braking lol. But better have one on hand just in case.

Quick question; bleeding the brakes at the end. Do I only need to do the 2 rears since that is where I am replacing pads/rotors or at all 4 wheels?

You don't have to bleed the brakes if it has been done recently or within the last year or so.

Note on Zimmerman rotors: I bought some cross-drilled Zimmermans for my first brake job and they didn't last long at all. Maybe five months tops. The holes weren't all that impressive looking, either. I went with OEM blanks this time around.

Really?? I thought every time you service anything brake related you have to bleed them?

According to service records I have here, the front pads and discs were done in March 2011.

So your saying I will not have to bleed one this weekend when I do the rear end?

If you have solid brakes now

And you change the pads properly, you will not have to bleed anything. No one here bleeds their brakes when doing a brake job unless you have a problem.
You need to find a good brake DIY and study.

This is what I was looking at --> http://m3.madrussian.net/diy_rear_brake_pads.shtml

He does not say to bleed, but I've seen other members on here talk about it.

What you need to know

is to not let the calipers hang by the brake lines. Tie them up securely.
After you take out the old pads, ease the pistons back into the caliper cylinder while monitoring the brake fluid reservoir level so as not to overflow the fluid.
This whole process does nothing to necessitate bleeding.
Be careful, go slo and think as you go.
