Changing REAR brakes?

[BigFas]

Is changing the rear brake pads and discs as straighforward as the fronts? Need to do mine pretty soon, but I know the handbrake mechanism resides behind the discs so don't mant to dick around with that.

However, if it IS straightforward, then after yesterday, I'm good to go :)

i was asking the same question a month or so ago and to be honest it looked a bit complicated on the DIY guide i got from www.bimmer.com but but after the replied from here and a Juber saying his done it too! i thought i can't be hard at all and gave it a shot. I took my time doing it carefully etc. and done both side under an hour.:D

[BigFas]

Damn. If Jubs can do it. I'm all set :D

What you will need is a caliper winding tool. Basically, because of the handbrake system you cannot simply push the caliper back in, you need to twist it instead but besides that... just the same as the fronts :)

Whoa. Don't start complicating shit :confused:

i followed this guide:

i didnt need any unwind tool and i have the same car as you.

lmao Fas @ complicating things, you can probably bodge a tool together to wind the caliper back, I usually do, it's too much effort buying one specially :p

Whoa. Don't start complicating shit :confused:
e46s don't need a caliper rewind tool, just use a c clamp (1 quid from Tescos).

- release hand brake
- remove 2 bolts from caliper to slide the caliper off
- remove the hext nut that holds the disc
- take disc off
- use c-clamp to push the piston back
- replace pads
- reverse and you're done

Even i've changed pads/discs...easy peasy:D

I used the guide from the madrussian website;)

[BigFas]

pukka. will get the bits in and do the work.

Will get my glamourous assistant Mud to manage the brake fluid level viewing analysis function

Fas if u want to borrow tools or brake fluid bleeder things u know where i am:) the hex bolt that holds the disc is usually a bugger as u'll end up snapping your alan key after first attempt:)

[BigFas]

not planning on needing fluid bleeder as I won't be dismantling any pipes, just straightforward pad / disc changeover. As for hex bolt, Halfords Chrome vanadium tools already in hand :) Tried Tesco stuff when I refurbed my rims, nearly ripped my hand off when the side of the spanner head ripped open! But genuinely appreciate the offer dude

Give the disc hub a good few whacks with a hammer to loosen the rust before pulling it out.

A man after my own heart :D take note guys, if it doesn't move, hit it with the biggest hammer you can find :p a sledge is fine LMAO :D

[peppernick]

As long as you don't do it at midnight like what we did to Durgesh's CSL. His neighbours came after us with the biggest sledgehammers they could get their hands on ..... LOL

Get some plus gas and spray the bolts if they are rusty.

Just bumping an old thread :)

Brake pad wear light came on last week so got myself down to the dealer today and picked up pads / discs / sensor for a grand total of £103 (including my discount). they also threw in some goodies for free. New retaining bolts, loads of brake pad lube and a massive can of brake cleaner! GSF wanted £140 for the same (pattern part) items

Watch this space. Mud and I are tackling this tomorrow. First proper use of the "Black Mamba" trolley jack!

[BigFas]

Sorted. What a fucking ball-ache :(

First time the discs / pads were changed in 4.5 years (i.e. since the car was new), and the discs were welded onto the hub!

Anyway, some hammer twatting and neighbours swearing at me because of all the noise, they're all done.

One thing though, even when the disc had broken away from the hub, I just could not get it away from the carrier, in the end I had to remove the carrier entirely, but I've not seen it mentioned on any forums / how to's etc.

Thanks for the help today as well Mud ;)

[benny boy]

Nice one at least all brakes are now in full working order how did it go with the jack lol

[BigFas]

the black mamba performed flawlessly. I'm going to buy a fleet of them, they're that good!

[robinh20mrv]

dot 5.1 and some aeroquip hoses next fas? ps you were so right about coilovers!! :)

[BigFas]

braided hoses and fluid were done ages ago.

The only reason I posted was I'm chuffed that I've managed to do it solo. 12months ago, I would have paid a shop to do it, but am enjoying getting my hands dirty more and more.

[peppernick]

Well done!

The most taxing part with changing brake components is to remove parts that are 'welded'. Don't know why BMW never grease any of the metal-metal components when the car left the production line. Will definitely make life a lot easier during routine mantainence.

I think its safe to say that if it where not for me this job would not have been completed!
