Had the 3 locking tabs on my south bend hyd 1.5 break off yesterday. 2nd one its happens to. I contacted them and they are going to send a "repair bracket" which i guess pinches the master cylinder between the 2 brackets. Does anyone have a part number or link where else I could get this, need one for another truck

I have never heard of this. Could you at least show a photo of what you are talking about, please?

Currently, I have aluminum hydraulics on Beast, which are AutoZone lifetime warranty hydraulics. All are made from aluminum and hold up much longer.

Pictured is the bracket they sent, and how or installs on master cylinder. I had to pound the studs out of the factory bracket and they supplied threaded rod, external tooth washers and nuts to hold both brackets together.

@Mopar1973Man are the aluminum hydraulics you have oversized? This is a south bend HYDx1.50. I have a stage 6 dual disc clutch so the oversized hydraulics make pushing the clutch so much easier than a stock set up.

I'm on a Valair dual disc clutch on both trucks. Beast, I got the AutoZone master cylinder and slave on. Yes, I'll admit it's a strong push on the pedal for the throw. Thor still has the Valair hydro's, but a much lighter pedal throw. Still feel the heavy springs of the pressure plate.

Yeah, the mounting tab to break off means it's a lot of pressure pushing on the hydro's master? I've got to ask whether you over-adjust the rod? There shouldn't be any mechanical force on the master cylinder body unless the over-adjusted rod was allowing the piston to bottom out in the cylinder, causing the break mounting ears. Or is the plastic so weak that constant cycling of the clutch caused it to fail by breaking?

I believe it's just that the plastic got weak. I'm fairly sure that I've got it adjusted correctly according to South bend's instructions.

I've heard the Valair dual disc's are very quiet, especially compared to south bend. Would you say yours are quiet?

Depends on the series.

Thor has the quiet towing dual organic clutch disc and it is quiet. This has the spring kit on the center disc to reduce rattle noise.

Beast has the performance series dual organic clutch disc and its rather loud throw-out bearing noise and center disc rattle.
