Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Good idea to fit brake reaction bars?

Yes, one or two washers I agree.

But for a difference of 15mm? Now it‘s a little adjusted down to a gap of 3mm. A difference for washers.

One side is in position, ready for drilling a hole, the other side the tophole of the BRB is to small for the
greasingscrew.

15 mm isn't tension it is far more. The bodger in me says fit a nut under the bar. Buty why is the gap so large.

the lower nut and screw is metric M8 or 1/2“. Such nuts are about 7 or 8mm high (a little bit more than 1/4“) so you need two nuts
to close the gap. A little bit out of a good idea I think.

So I bend the bars in a better fitting shape, now one side is matching, the other side needs one washer.

Tomorrow I‘ll fit the wheels and will look if they don‘t rub at the bars.

Than only drill the holes.

On later cars with camber adjustment and necessary rounded end kingpins I would always fit the two shaped washers (well greased) last, directly under the top nut. The action of tightening the nut will allow the two washers to slide against each other to accurately compensate for kingpin angle. Note it's been known for such washers to explode if this is not allowed to happen!

Wolf performance publish this guide confirming advice on washer location for all.

My car was spec'd with BRB's from factory new (and fitted as above) but if retro fitting and in event of outer end not lying against or close to chassis during test fit, I would simply bend one or both flattened ends to suit. Sorry but fitting washers or spacers is a bodge. The thickness of a standard washer gap can be ignored. More important it's bolted directly to chassis.

Oh, thank you for the guide!

And: the idea with the paperboard was very good! We fitted the BRB today, only with two washers at the chassis. But
on the top I do it in the wrong way. So once again.

But in cause the clutch doesn‘t work no testdrive possible. Also I hope about the weather.

I ordered up a set of BRBs from Williams as I have the wings off at the moment. The set does not have a washer welded to one end but the hole for the oiler bolt is elongated. The lower end of the BRB seems to fit onto one of the fixings for the tyre rubbing block. Is the elongated hole there to take care of any "misalignment" of the crossframe? And does this compromise the solidity of the fixing at the oiler bolt?

From memory the factory BRB's don't have the welded hole reinforcements either. Not sure if your tyre rubbing blocks were a factory fit but probably a coincidence the mounting holes worked for your BRB's. Regarding elongated hole for kingpin bolt fixing, it's not ideal but the washer underneath bolt will spread the load and hold them in position as it forms it's own index on BRB when tightened. You can always check these witness marks at kingpin/bush change to see if its remained in position.

Finally remember BRB's remained a factory option to the end of Classic production.

When I understand right there are „oval“ holes fo fit the BRB?

I discuss this idea with Keith at BHM. The idea of the BRBs is to give more stiffness. If you‘ve got oval holes the BRBs can move and „work“ in this area, this wouldn‘t be good. In this case you reduce the stiffness.

Just back to the MOG to fit the BRBs like the guide.

On the top I fixed it: undo the greasingscrew, put the topmount of the BRB on the top of washers and than fix it with the screw again.

The guide shows this would be wrong… so once again. But than I wonder. The welded washer matches exactly the size of the greasingbolt. The „suspension specialwasher“ are much bigger the the BRB. So you fix a small part under a bigger part?
In mechanical sence I couldn’t believe it.

But if the guide shows it…

Than the downscrews. Caused by the new top fixingpoint the drilled holes where wrong. The result: oval holes. Also not the best idea.

So I had a call to Britain to a man with THE knowledge.

Short summary: I had fixed it in the correct way. Undo the greasingscrew, leave the factory washers in position top the BRB and screw it together.

Clutch fixed today (another story) and testdrive.

WOW ( World full of Wondering) what a difference! Much better roadholding and I think also much softer suspension!
