Today I finally got time to install the rear calipers that Roy has renovated for me. First I pulled the hubs in order to install the shiny new brake disks. But, what the #%&#. The bolts holding the disk to the hub, that I had taken out, did not fit the new disks. A thread gauge confirmed that the bolts were 10 mm/1,25 rise, but the holes in the disk had 10mm/1,5 rise. A call to Simon and they checked that new bolts and disks should be 10mm/1,25. But they had sent me the disk, so they of course offered to send me a new set of disks right away. All fine, but the day was blown Worse, the car must go to the MOT on the 13th. Cross my fingers the new disk gets here and weather permits doing the replacement in time. (Car is without wheel outside)

10mm x 1.25mm pitch seems to be a strange French quirk. Here in the UK, if you ask for a 10mm fastening, you will always get 10mm x 1.5 unless you specify something different. French cars, not only Matra, but Citroens, Peugeots and Renaults always use 10mm x 1.25. Obviously the person who re-manufactured the discs didn't understand this. Had I been in your situation, I would simply have gone round to my local stockist and bought some 10 x 1.5 bolts rather than go to the trouble of sending the discs back. You may find that the replacements have the same fault.
Simons has not asked for the disks back. Not worth the cost, I guess. They are sending me new disks anyway. About bolts, you will have noticed several 7mm X 1mm in the Murena. Those aren't seen on many other cars.

Probably this is the new batch made in Hungary. They all have the same problem I presume.
I do not think so. I have bought a pair in Hungary and those were perfect. Otherwise human factor can cause any fault during production. The Hungarian rear discs are available at Carjoy. I do not think that Simon has the same source, but I am not sure in it. I know Laszlo was busy preparing a batch from Hungary around 2010. Normaly you see the the items come available from all sources in Europe. I don't know if they still co-operate since Ruud is gone at Car-joy. The disks were unavailable for some time. That's the reason why I had to switch to Alfa disks. They work awesome so I will run them till they die. That can take more then a decade or 2 Greet herman

Quote --------- Good thing I have retired or I would never have time to keep up with the repairs. ========================================================== Just buy another Murena, and it starts looking like work. It is important to look at the hoses and brakelines. Most were gone on the cars I have and 30 years old Some didn't even pass fluid.

Next comes replacement of the gaiters on the rack and pinion steering.
Well the gathers are replaced with no problems. That was the easy part. Getting the air out of the brakelines and calipers was next. Had decided to do it without waiting for the new stahlflex hoses I had ordered. The vent screw on the left banjo bolt came loose grudgingly. Airing it out did not go easy and is still not complete. Reason being that the stuff coming out was like mayonnaise rather than brake fluid. I will have to flush the whole system. The vent screw on the right banjo bolt broke . So I loosened the banjo bolt and wrapped it in tissue paper and then pumped lots of fluid through. After tightening it up the brakes seemed pretty firm. But I will do it again after the stahlflex hoses arrive. Update. Well the hoses did arrive. But the supplied banjo bolts do not have a vent screw. Worse. they have the wrong thread. they are 10mmX1mm where as the calipers and original banjo bolts are 10mmX1,25mm thread. I have written for a replacement. Hopefully they have them in stainless steel like the ones they sent. If not, I have found a pair on ebay that are 10mmX1,25mm with vent screw, but not stainless. We shall see. The result of all this is that the car still has not been to its MOT. It should have been there on November 13th. I have called to ask what I can do. They say they will send me a (stern) reminder between Christmas and New years and after that I have 2 weeks to get it passed. If not I will receive a 2000 DKK. fine. Optionally I can turn in the license plates (un-register it ) Then I will have to buy new plates for it when I get it running. Still cheaper than the fine, so we shall see. It is going to be a race between getting new bolts, airing out the brakes and getting through the MOT before the deadline. Wish me luck. PS. Anyone want to buy a Matra Murena 2.2? Lots of spare parts.
