Brake Mystery
I just returned home from a 10 mile drive. I drove slowly close to home so as to require minimal braking. On my drive I (carefully) felt all the brake discs with my finger through the gap in the wheel spokes. The rear offside disc was very hot. I raised both rear wheels using the rear jacking point. I started the engine then tried stabbing the brake pedal and long steady presses. Under all types of repeated braking both rear wheels rotated freely as soon as the pedal was released. I also tried applying the handbrake. One click made both wheels hard to rotate by hand and two clicks made both wheels impossible to rotate by hand. As soon as the lever was released both wheels rotated freely.

Sticking calipers perhaps? Mine were the same a while back, cleaned the pins and regreased.

With lifting the car at bothsides the rear arms have lowered to the extended travel of the shock absorbers , and are not in the normal road traveling position Your hand brake in the position your arms are in as only two notches to solid wheel lock and is actually quite tight . It is possible that in the normal travelling position of the arm as the handbrake cable routes it is in fact tighter than it is now and is binding The way to check this is to sit axle stands under the arms and let the arms take the weight of the car as it would on the road and retest I hope you understand what I mean Not seen this before with a Rover 75 /Zt but i have with other makes |

Steve, I understand what you mean and you may be onto something. I will try it tomorrow and report back.

This morning I supported the rear of the car under the arms. This made no difference to the handbrake operation. Both wheels were completely free with the lever down, it was possible to turn wheels by hand on one click and not possible to turn wheels by hand on two clicks. I wonder if when driving along the road and the rear suspension is compressed beyond the normal rest position if this is affecting the handbrake cables and intermittently applying the hand brake. This would be difficult to simulate when the car is stationary.

In my experience your handbrake has been adjusted to be far too tight or the mechanism requires cleaning and lubrication. As a guide, four clicks for the wheels to be locked is more practical and realistic. Simon

I did mentioned brake cable tight in first post , was my main reason for getting to re test I agree 3 to 5 clicks, brake rub to wheels locked is realistic Last edited by TourerSteve; 17th October 2021 at 08:23.. |
