Just checking the bias valve is the same as compensator as it seems on the rear brake thread both get mentioned.
Car faile don rear parking brake efficiency last year and pads were worn down like rears were locking on. Calipers were quite new so replaced pads and handbrake cables and got through.
Now rear brake and parking efficieny are below pass level this year and rears and nearly worn again so rather than keep on replacing calipers and pads I believe the bias valve is the culprit seeing as others have had same problems.
Is the bias valave the same as the compensator?
