Stupid Question Regarding Brakes

DTd5 · May 3, 2013

Can someone clarify what the arrangements are with the disc brakes on a 2003 defender 90.

ie: when you depress the brake pedal, should this cause the brakes to be applied to all 4 wheels equally?

or is there a bias towards the brakes on the front or rear wheels etc?

The 90 models had a pressure-reduction valve to limit the pressure to the rear brakes.

OK thanks, so the main braking is via the front...

Yes, but that would be the case anyhow as the weight transfers forwards when you brake. So if the force was distributed evenly the rears would lock up as the weight over the rear axle decreased. This is why the valve is in place on 90s.

110s being more stable in that way and having more weight I guess Land Rover figured it wasn't necessary on those.

Early 110 had the same regulator valve as 90's, it was the same as used in the classic Mini

(not Mk1)

Just out of curiosity where is the regulator valve?

master cylinder on later models, inline towards rear on early ones

My 90 one is on the drivers side below the master cylinder on the chassis.

My old 110 had it on the bulkhead below the master cylinders

I'll need to have a look for it. I never even knew there was anything like that on it so never hurts to know where it is
