Should I replace brake pads at 4mm?
Most pads start their life with about 12 mm of friction material, and most mechanics suggest replacing them when they get to 3 or 4 mm. You should replace your car’s brake pads before the backing plate begins gouging out the brake rotors — a complication that can make the job even more expensive.
Is 4mm bad for brakes?

How thin should brake pads be before replacing?
6.4 millimeters
Your brake pads’ minimum thickness should be at least 6.4 millimeters. Above all else, you do not want the thickness to get any less than 3.2 millimeters or it will be very dangerous to drive.

Is 6mm good for brake pads?

Most brakes pads that are worn to 3mm is recommended for immediate replacement of the pads and resurface or replace the rotors.
How long will 1 mm of brakes last?
Registered. The brake pads usually start with 11mm. You have 4mm left (replace point is 3) so you have used 7mm in 33k miles. At your rate it will take 33/7 or about another 5K miles to wear another 1mm.

What is the legal limit on brake pads?

Most manufacturers recommend changing your brake pads once they get to 3mm, however the legal limit in the UK is 1.5mm.
Do rear or front brakes wear faster?
Your front brake pads will also wear down faster than your rear pads. The front of your vehicle handles a lot more weight transfer as you brake, causing more wear. Over time heat and friction also contribute to brake pad wear.
How long can you drive on 2mm brakes?
At 2 mm pad you can be sure that you need to replace pads, but the rotors may still be above minimum thickness, but you let it get to 0mm pads, rotors are guaranteed to need replacement. Has more to do how you use the brakes and not the miles. 2mm can go from 2ft to 2000miles.
Should I replace all brake pads at once?
But, when changing brake pads, should you do all four at once? Well, first, you absolutely should replace both front or both rear brake pads at the same time. Unless something’s really wrong, one should be wearing out at about the same rate as the other.

You should follow the manufacturer’s recommended minimum brake pad thickness. In most cases, you’ll want to replace brake pads when they get down to about 3mm.

How long do brake pads take to wear down?
