+1. And we've heard of some CV joints going out already. Not a massive number, but some.Nubo wrote: The one thing that comes to mind is Constant Velocity joints. If these are wearing, you can hear a repetitive clicking that will first become noticeable during acceleration/deceleration and usually more pronounced when turning in one direction.
Hi I have aualdep wrote:I have a 2012 SL Leaf. Every time I let off the electric pedal & press the electric pedal, I hear a moderate clicking noise .
I never noticed it before because the radio or road noise covered it up & I'm getting old. But my younger son heard it 1st.
The Nissan mechanic said it was the brake pads shifting. Anyone else experience this?
AFAIK the design of disc brakes hasn't changed much and on the cars I've worked on the pads always make a swoosh sound when you free spin the tires. It's not enough to cause heat, drag or wear but enough to hear. If the caliper retracts when you let off the brake pedal there still isn't anything they retracts the pad since the caliper and pad are floating so it would still stay in contact.garygid wrote:I believe, with properly adjusted disc brakes, that the pads
should NOT touch the rotor during normal non-braking operation.
The cylinder plunger should be pulled slightly back off
the back of the brake pad, by the rubber gasket/seal around the
cylinder, which should allow the pad to move back off the rotor.
Any touching would produce a lot of heat, some drag, and
some wear on both the pad and the rotor.
But, maybe that was in the "olden days"?
