Changing Brake Discs/Hoses 944lux - advice/tips?
Discussion
Hi everyone,
I've got to change the brake disks and fluid on my 944 2.5 lux tommorrow, so I thought I may as well pop some braided hoses on to replace the old rubber ones while I was at it (got Goodrich braided hoses from the nice people at design911). I just went for standard Zimmerman discs and standard OEM pads, as I couldn't see any massive benefitin fitting uprated pads or discs, seeing as how I really want to pop a 993tt disc/caliper conversion on when I get the funds available :D:D:D:D:D (It'll be over a year away at least :D)
I've heard you should bleed the rear brakes first, and do theclutch as wellas it's all off the same master cylinder, but I was wondering if anyone else has any advice or tips for this I should try out?
Cheers,
Fatboy

I just had this done on mine but since I paid someone to do it I can't really offer any actual advice.
However. re. the 993tt brake upgrade I think this will be difficult on a Lux as you will have to replace the suspension strut assemblies as well. Its possible on a 250 turbo wihout replacing struts but any other 944 (I believe) will be a mega project.
Certainly it proved prohibitive for my S2, so instead I went for cross drilled discs all round; new OEM pads; Goodrich braided hoses; Royal Blue brake fluid; and a total caliper overhaul, including new seals, pistons, plates, removal of corrosion and a repaint.
So far I've only driven it back from the indie (about 2 miles) so can't really comment on the performance, but they look the DOGS!
However, now I've paid the bill ... that was pretty pricy too ...

The cylinders are seperate, as I had to replace the clutch master on my old car, so you shouldn't have to bleed the clutch as well. I thought from memory they had separate reservoirs as well?
I think your supposed to start with the caliper furthest from the master cylinder and end with the closest.

Cheers for the replies - I wasn't sure about which rear wheel to start with, but that makes it obvious
That's something I hadn't heard - bugger. Might just get on to the nice people at AP and see what they can offer instead then
Sounds very nice though - got any pictures?

A nice long breaker bar is highly recomended for the caliper bolts and then a torque wrench for tightening them back up after wards, you dont want them to be too tight/loose !
Oh and to seperate the old disc from the hub, undo the nuts then hold at an angle (disc at the bottom) hammer around the face of the disc to free it from the hub.
Regarding upgrades Willwood do a four pot caliper conversion which fits the original discs.
To upgrade to Turbo/S2 discs & calipers, involves fitting new spindles, hubs etc and is pretty involved.

I've got a torque wrench, really didn't want to overtighten them
Cheers for the tip on the discs.
I've never had a car that stopped as well as this one, so it's not that I find the brakes wanting (they're amazing), I just quite fancy some ridiculously huge brakes
Woohooo! Penetrating fluid (lots) and a 450mm breaker bar did the trick! Got the bloody caliper bolts loose at last
Only thing is that the bleed nipples appear to be rusted solid (already used the penetrating fluid) on both calipers, and one of the hoses is rusted solid onto the caliper...
I'm starting tothink it may be an idea to get some reconditioned calipers (or get mine professionally reconditioned) - just got to find out what it will cost...

I'll PM you - the number is too frightening for a family channel like this
Having done 300 miles on my new brakes over the weekend, I can confirm they not only look the dogs they are the dogs! Fairly sure there's a bit more bedding in to do, but really a massive improvement over the pre-overhaul situation.

Cheers for the e-mail Dan.
Not only does it look like the bleed nipples on both calipers are completely siezed (no amount of penetrating fluid seems to have an effect and I've already almost rounded a corner off), but the passenger side solid brake line fitting rounded off when removing the flexi hose - ARSE!
Anyone know a good place in or near Warwick where I could get a replacement made up? (I've got the line out completely - thank god it was the short passenger side line!)
