Front to rear brake bias

[mr.ots 10]

Does anyone have the specific specs on the front to rear brake ratio? I've fitted a new rear proportioning valve and I'd like to set it as accurately as possible using line gauges.

 

I've done a lot of searching and the closest info I could find suggests it's somewhere around 65% front to 35% rear.

 

Any definitive answers out there?

according to the Bently manual

 

Front axle = 50 bar

Rear axle = 27-33 bar

 

Front axle = 100 bar

Rear axle = 48 - 54 bar

Thanks for the info.

 

So taking the centre value for the rears that works out at 62.5% front bias at 50 bar and 66.3% at 100 bar so 65/35 was about right.

 

I'll get adjusting 😊

Thanks for the additional info easypops.

 

I also found this link which gives the procedure for setting the regulator.

Time permitting, I'll give this a go at the weekend.
