Why Does My Car Squeak When I Reverse?
If your car has suddenly started making a squeaking or high-pitched noise when you reverse, the brakes are one of the first things worth checking.
One common cause is the small metal brake-pad wear indicator fitted to many brake pads.
As the friction material on the brake pad wears down, the indicator gets closer to the brake disc (rotor). When the pad reaches the point where the indicator contacts the rotor, it can produce a noticeable squeaking sound.
Why does it squeak when reversing?
Many brake-pad wear indicators are positioned so that they make their warning noise more noticeably when the vehicle is travelling in reverse.
So if your brakes are quiet when driving forwards but squeak when you reverse, a worn brake pad and its wear indicator are a likely explanation.
It isn’t guaranteed to be the cause. Brakes can make noises for other reasons, including moisture, surface rust, brake dust or other issues within the braking system.
The important thing is to have the noise checked rather than guessing what it means.
Does a squeak mean I need new brake pads?
It might.
If the wear indicator is making contact with the rotor, the brake pads are getting low and should be inspected.
But there is an important distinction between being told your brake pads are getting low and suddenly discovering that they need replacing.
You should already have had some warning
If you’ve been having your car serviced regularly, your brake-pad wear shouldn’t normally come as a surprise.
During a proper vehicle inspection, the condition of the brakes should be assessed and you should be told when the pads are getting towards the end of their useful life.
At Motorfix, we’re not particularly interested in giving you a percentage wear figure just because we can.
The question we’re really asking is:
Will these brakes comfortably make it to the next scheduled service?
If they will, we’ll tell you.
If they’re getting close, we’ll tell you that too.
For example, we might tell you:
“Your brake pads are getting low, but they’ll comfortably make it to your next service. We’ll check them again then.”
Or:
“Your brake pads are getting close to replacement. We’ll probably need to do them at the next service.”
That gives you time to plan.
Then, when the next service arrives:
“Yep — they’re due now.”
You shouldn’t be thinking:
“Where did that come from?”
You should be thinking:
“Yeah, you’ve been telling me they were getting close for the last couple of services.”
What about the service you just had?
If you’ve recently had your car serviced and you’re now hearing a brake noise, have a look at your last service invoice or inspection report.
What did it actually tell you about your brakes?
Did it tell you whether the brake pads were getting low?
Did it tell you whether the discs were in good condition?
Did it give you enough information to know whether the brakes were likely to make it to the next service?
A useful vehicle inspection shouldn’t just identify things that need doing today. It should help you understand what is coming up next.
Why we don’t want you coming back between services
One of the goals of a good maintenance program is to make your motoring easier.
We don’t want you having to bring your car back to the workshop every few weeks because another maintenance item has suddenly become urgent.
If we can identify something during your regular service, tell you about it early and monitor it at subsequent services, you have the opportunity to plan the work at the right time.
That means fewer surprises and fewer unnecessary trips to the workshop.
It’s not about finding something wrong with your car every time you see it.
It’s about knowing what condition your car is in and what’s likely to happen next.
What if the squeak isn’t the brake-pad wear indicator?
There are other possible causes of brake noise, so the sound alone cannot confirm that the brake pads are worn.
Moisture, surface rust, brake dust and other brake-component issues can also produce noises.
That’s why a proper inspection is more useful than trying to diagnose the noise from inside the driver’s seat.
If you’re hearing a new squeak when reversing, we can check the braking system and tell you what’s actually causing it.
Making your motoring journey easier
At Motorfix, our job isn’t simply to fix things when they become a problem.
We want you to know what condition your vehicle is in, what is coming up and whether it is likely to make it comfortably to the next service.
That way, when something eventually needs replacing, it shouldn’t be a surprise.
If your car has started squeaking when you reverse and you’re not sure why, let Motorfix check it out. We’ll inspect the brakes, explain what we find and let you know what, if anything, needs attention.
