| just realized the bottle I bought last year is synthetic and I'm not sure if it's synthetic or silicone that destroys the rubbers
any advice greatly appreciated, having a friend coming over tonight to help bleed everything after caliper and master have both been off the car for repairs
(big thanks to Melle for helping facilitate parts delivery from NL at reasonable prices)

| | As far as I'm aware it's DOT4 for the early and late 96's. I believe that you can mix the two though but I'm sure someone will be along here soon to advise accordingly. |

| | Thanks Chris - Workshop manual states DOT3 or 4 or SAE J 1703 (whatever that is??!?) but was probably written before synthetic even existed.... | |

| You can freely mix DOT 3, 4 and 5.1; as far as I know DOT brake fluid is always synthetic and the only difference between aforementioned types is their boiling point. DOT 5 is silicone based and can't be mixed with the others. I always use DOT 4; DOT 5.1 is high performance brake fluid, which I suppose for a road car is not worth the extra money.
By the way: who doesn't like the look of a fresh caliper! Did you need to do any welding/ grinding on it?

| | Thanks for the info Melle - bracket was ok (as far as I could see and compared to the brackets you posted images of a while back). Interestingly there wasn't enough on the Swedish Car Parts repair kit pin to peen it, so the guy I give all these little jobs to do, welded it in place instead. He was questioning why it wasn't a threaded set bolt with a captive nut, so it could be potentially tightened as it wears (which I thought was a good idea) so let see if his work has....worked! | |

| I've seen many welded ones; I always assumed that at some point Saab switched from peened to welded or the other way around.

| | That would explain why some of the repair kits measure differently, one of a very few things I hadn't resolved for the kits I was going to have made, until somebody pointed out the difference! | |

| Would still be great if you would go ahead with them!

| The service manual in a 2002 SAAB 9-5 says don't use synthetic DOT5, to use only DOT4, so there must be a difference.

| That's correct, DOT 5 is silicone based, see one of my earlier posts in this thread.

Because DOT 5 is silicone based, DOT 5.1 is not.
