Hello everybody.

First post for me on the forum.

I was reading the forum for nights and found lots of nice info and tips for the mini.
I drive on daily basis for the last 3 years a 1275 spi mini. We bouht it new in 1990s and has 60.000 kms.

Except from the rust (i am living on the french apls with winter salted roads), a smotha ride kit,  a radiator hole, an alternator, a launcher and the end of the exhaust, the mini is solid as a rock !!! and it is so funny to let far behind lots of modern and powerfull cars on a montain and snowy road !

 

I am looking for some information about the brake balance.

Since i have changed front disk and pads plus rear shoes, i fell that the braking balance is wrong.

While braking i feel the bottom of the car going down as when i am using the handbrake.
On wet condition and heavy straight brake i fell that the rear whells are bloking first.

As basic braking used to be 80% front a 20% rear i am guessing if there a braking balancer to setup.

 

How can i verify this ?

Is it a master cylinder issue ? or Servo issue.

 

Has anyone ever faced this behaviour ?

Any clue could help me.

 

Thanks for all.

The brake bias is fixed on the mini, however, it maybe air in the system which is causing you a problem, and if you've changed disks, pads and shoes recently also a material issue.

 

Bleed the brakes ( always start with the wheel furthest away from the master cylinder, and work round to the nearest )

 

If that does not help, I would get you brakes tested ( in the UK they are tested as part of the MOT, I believe you have something similar ? )

 

It may be corrosion on the calliper pistons, or just the wrong disk or pad material for your driving conditions.

Thank for this quick answer.

The brake maintenance has been done by a car specialist.

Caliper has been replaced 1 year ago...

I will ask the garage to check all of this.

 

The brake bias is handle by the servo or the master cylinder ?

Does a spare spare exists on wich we can manage the braking balance ?

 

Thanks for your help.
