Kaj , the sensors I recently purchased were a Sebro brand and the Porsche part number was 944 612 365 00, 01, or 02.

Probably bought from Pelican Parts (dont recall now) but the usual parts houses should have them.

Hopefully the Porsche part number will help identify what you need.

It really should not be that complicated. What I need from them is a two brake pad sensor. What I get is a one brake pad sensor. At this point I am just waiting for more comfortable garage weather as I have a back up courtesy of Matt. Looks like sun is coming out next week. Maybe there is a chance soon that we could get started on this.

Started the much delayed brake pad and rotor replacement today....Hallelujah!!!!......Got to the part of removing the two bolts that holds the caliber in place. Realized that I could not use my 19mm socket as it was too long......After some calls I found out that my 3/4 inch, which is short, would do the trick........God, I wish everything could be metric....it's is so much easier to work with. Anyway those bolts are tight and I will continue to work on them tomorrow. Yes the old brake sensor broke (as warned) but I have replacements.......So, let's see what Wednesday deliver of surprises.

tech note - you must use a torque wrench on those bolts.

Indeed Flash. 93lbs/foot for the lug nits and 63lbs/foot for the two 19mm caliber nuts.

 

Left wheel completed today. Moving over to the right side.

 

OBSERVATIONS: The 19mm caliber nuts where a bit difficult to loosen. I did crank the steering wheel all over to the right to make space. Did get them off. The old brake pad sensors are useless and just about impossible to get out. Always buy new ones. They are cheap. Re-using the squeak dampers in my case was impossible. They where impossible to get off the brake pad. Keep in mind brakes have never been replaced in this car's 25 year history. I am using a different approach to the squeak issue but not sure if it works, time will tell. The original squeak dampers for this car are pricey. Hoses where in good shape and no issues with the bearings. A lot of time consuming cleaning went on here. The caliber, wires etc. PS: Good time to clean the inside of your wheel now that it is off. Don't forget to add a small amount of sealant grease to the o-ring of the sensor before plugging it in. I also added a very small amount of grease to the top and bottom side of the pads being very careful not to touch the braking part of the pad..

TIME: One wheel 8 hours over 2 days. ( I move slowly making sure I don't make mistakes)

MISSION COMPLETE. Finished the right side in 4 hours. Nothing special to highlight. The pad lock spring was a bit of a pain to squeeze back in. Lubricating the top and bottom of the pads is a must to be able to slide them in. Also the two pistons on each side should be cleaned and lubricated. Remember to slide the wheel all left/right to gain access....and again tightening the bolts correctly. 95lbs/ft for the lug nuts and  63lbs/ft for the two caliber bolts.

Test drive and brake test. Remember to pump your brake a few times before you venture out. Last thing on the agenda is a complete flush and replacement of brake fluid.

did you repack the bearings while you had the rotor off?

think that might have been a bridge too far

No clicking, no strange sounds. Bearings packed and in top shape.Last thing on the list is a flush of the fluid. Will do that on Tuesday and the Amethyst Dazzler should be ready for some spring time cruising.........Can't wait to get the top down....will wait ..it's snowing in Scottsdale and in San Luis Obispo.

Well, it has been a year plus since I did the front brakes. Now the rear has been ordered. I will replace both rotors and pads. The rear rotors have a deep lip in them and the time has come.

Good way to go Kaj.

I just changed my front rotors, pads (original Porsche), fluids, wheelbearings, torsionbar rubbers + hardware and tyres.

Didn't check the bearings state, but i suppose after 29 years it's just time to refresh them.

And some other important stuff

I just finished my front brake overhaul last weekend - i went with the EBC pads and coated rotors.  Ran-into some of the same issues with the pads - they were too thick to use the stock Porsche pad dampers.  Also found that the 'red-wire' lead of the pad wear sensors had gotten shorter than OEM, which meant that the metal clip on the pad harness was useless.  Also did new wheel bearings and re-greased the hubs.

 

When we bled the brakes on the front calipers, the inner bleed screw was fine - the outer bleed screw didn't bleed nearly as-much.  My buddy running the pressure-bleeder didn't really like what he saw, and was concerned that the caliper was gummed-up.  Or, this was natural because of the ABS (he has a 944 Turbo, and didn't have similar results on his car).  I'll be doing the rear pad/rotor swap this weekend, but I did replace the lines already so the brakes could be fully bled ahead of time.   Both inner and outer bleed-points on the rears didn't show this issue that the front brake calipers did.  Thoughts?

Hello

I'm just about to start my rear brake pads/rotors and wondered what your different approach to the squeal pads was?  I don't really want to add 50% to the cost by buying 8 of these little things, 30mm and 28mm I think they use? I was planning on re-use with maybe some 3M high temp adhesive or possibly the 3M universal anti squeal shims.

I reused the old ones and put them on the adhesive anti-squeak pads. 2 years in and no problems whatsoever.

EBC pads are thicker as they already have a pad on the back for anti squeal, no need for the shims,

Same for original Porsche pads 951.351.939.08, they have an anti squeal plate on the back.

I did buy the other ones as well which cost me 44 euro for all 8.

 

Still have them if somebody is interested.

Instead of the two pad rings I used Permatex Disc Brake Quiet on the the StopTech pads. It worked flawlessly now almost a year later.
