Rear caliper / handbrake issue

(1/3) > >>

DBXdarkangel:
I'm having an issue with my passenger rear handbrake not holding the car. A few months ago on a trip back from London I notice a metallic tinkling noise coming from the passenger rear when the window was open at the back. When I pressed the brakes the noise went away but upon looking at the rear wheel it was black with brake dust and the rest of the wheels was fine.
I've took the wheel off and disconnected the handbrake cable to make sure the lever is moving fine and seems OK with a pry bar. I've also bought a replacement caliper, brembo discs and pads all round as mine are well shot.
My question tho is if the brake dust is a sticky caliper dragging then why is the handbrake not holding it?. It will work if I really yank the handbrake on but not fully like it used to.

What do you suggest I check? I did have the handbrake fully on and when I cracked the wheel nuts the wheel still moved a tiny bit. Is it the handbrake cable too?
I'm gonna take the back wheels off and jet wash the calipers and surrounding areas then lube the handbrake lever just to check

You could have 1 cable stretched more than the other very inexpensive and easy diy  I wire brushed both rear calipers before fitting new cables Now perfect.
ps The pagid cables from ecp do the job just as well

DBXdarkangel:
I'm starting to think you could be right. Gonna take out my centre console, cd multi changer and armrest as I've seen a few YouTube channels showing its a right pain lol. Think might be worth to replace them both when the discs and pads get done.

I've still got this task to do - ended up with the pagid cables for car parts for less, they look suspiciously similar to the QH ones that are even cheaper on ebay.
Someone recently on here managed to rip out the guide tube to the HB lever as the cable and tube had tried to become one.

I have a few posts up about my caliper / cable / tube replacement. Worth reading. Basically, I think it is worth cutting the end off inside the car before pulling through from the outside.

I realised that the steel cable was not moving inside the outer on one side. When lifting the handbrake the cable was actually pulling the outer and the inner at the same time, I’m not 100% sure in retrospect if I needed the caliper.

Worth lifting the rear of the car (both sides) and pulling the handbrake click by click to see if the strength of the handbrake is the same on both sides. Once you have done that, get the wheels off and take a good look at how much the caliper lever arm is moving and what the cable is doing.

Everything is straight forward unless the cable gets stuck inside the tube. :smiley:
