do you mean...the brake pump for sage blm is designed in such way that when brake apply the rear take the braking the most? my other jap car Honda and Toyota..did not experience this before. always the front take the heavy braking and the rear wear is minimal.
The rear braking force is less than the front and I believe what you trying to ask is "is the rear brake force the highest"
The rear brake cylinder is prone to leaking due to brake dust buildup in the drum system as the brake dust has no way to escape in the drum. If you are a DiY guy you can remove the rear wheel and use a hammer to slightly hit the drum to remove it and clean up the brake its inside the drum.
And also to not confuse yourself and others. Below is the correct term to used to describe the brake components
Master pump - is the main pump at your engine bay that makes your brake system works.
Rear brake cylinder - the brake pump at your rear drum brake that work the brake shoes.
Front Brake Caliper- the caliper that works the front brake.
