About to do brakes...

[supersport]

I am about to do the rear discs/pads + brake fluid. Other than diss/pads/fluid and wear senors is there anything else I should be replacing? I think I am going to stay with OEM parts, do you have any recommended suppliers?

I am quite looking forward to this next adventure in looking after my own car.

I'm in the same boat as you, have just had some ATE discs and pads delivered and need to pick up some brake fluid too. I believe that the wear sensors can be reused if they haven't worn through yet.

They have brake pad dampers in the front so I guess they are in the rear calipers aswell.

Also check for plate lift.

EDIT
Sorry thats a lie, your photo looks like you have a lux.

Nope, nothing more to replace. You may want to have some spare bleed nipples on hand in case you round one off, but that's unlikely if you are careful.

Make sure you have the right tools. A brake line spanner is a great asset. As is an easybleed kit of some kind.

Be careful with the fluid. But you already know that I'm sure.

The only advice I can add is a "whilst you're in there... " - it's got to be worth replacing the flexible rubber hoses on your car both front and back, unless they've been done since it left the factory. As you're going to the bother of bleeding the system, it's not much extra hassle to replace these and you'll find that a 4 x set of aeroquip/ goodridge is actually cheaper than Porsche OEM. Rubber hoses perish with time and even if you go down the route of simply replacing these with like for like you're braking system will improve and you'll have the peace of mind.

I'm curious as to why rotors are replaced everytime pads are replaced. It seems to be standard practice even though the Porsche manuals provide specs for turning, checking run out, etc. The repair places here like to replace wear sensors also regardless of wear on the plastic ends. Any comments?

An easy way of making money? The wear sensors I can understand, but rotors I really can't see why they would need doing every pad change unless corrosion is a big issue.

It shouldn't be. Before I upgraded to bigger brakes I replaced front pads twice and discs once. Modern cars seem to be one for one as they use softer steel which wears at a higher rate. Older non-Porsche cars i've had have always been two or three pads to one set of discs, but all modern normal hatchback and semi-hot hatchback cars i've had in the past 10 years have always been one for one. Unless the disc thickness remaining is greater than the disc thickness lost in the last set of pads then it is not worth leaving the discs. The OEM cost of a pair of discs for a 944 these days is equivalent or less than a pair of discs for an Audi A4 so not that expensive relative to the costs of running a normal family car.

+1 for Ezee-bleed. My gran could change brake fluid with that pice of kit.

don't forget if you're doing all that then you should really replace the pads retaining pins and spring clip []

Got a link to the parts?

Thanks chaps, lets see how it goes.

I am only replacing dics/pads because they are both shot.

They're difficult to find from anywhere but OPC, can't remember how much they quoted, will try and find
