General Sweaking Breaks

[JayDMistry]

I've not had my car that long but I'm getting annoyed with how much my breaks are sweaking.

I think I need to replace my break discs and pads. Can someone tell me what to look for when inspecting discs and pads, so I know if they need changing

I had a look at my rear discs and noticed a pretty big lip forming around the edge, is this normal

Thanks

There is a wear indicator contact on one of the front wheels . This is a good guide but not foolproof if you have uneven wear. I recommend inspection of the pads both front and rear. It is possible to rub off a small lip on the disc but there is a recommended 'thinness' of disc. New discs are not very expensive . When fitting new pads make sure they have anti-squeal shims fitted (not all aftermarket brands have them).

I agree with all that 850kd has said, just like to add this:-
Regardless of whether the existing brake pads are fit to re-use or if you are fitting new pads, clean any dirt/corrosion from the slots in the brake pad carrier bracket ( where the upper and lower 'ears' of the pads fit) and apply a small amount of copper anti-seize grease ( often called 'Copaslip') to these contact points, don't get any on the brake disc or friction surface of the brake pads, also clean and grease any caliper sliding pins before reassembly. You can also use a small amount of copper grease where any pistons contact the back (i.e. the metal part) of each brake pad if you wish but its not usually necessary if anti-squeal shims are fitted.

PS If you can get a look at nearly any past issue of Car Mechanics magazine you'll probably see in pictures what I mean by applying copper grease above, this mag. usually covers a service on a popular car each month and the work on brake pads is broadly the same on most cars. Hope this helps!

Lip is normal, mine have it too, and are still within limits (I measured them while changing the winter tires with summer ones).

I had a pretty bad squeaking from the rear brakes (which have even more life in them). There's this brake spray, which does miracles, at least in my case. I don't remember the name, can check later today. Obviously you don't want to spray the discs, but rather the mechanism of the calipers...My squeaking was gone immediately and just started to return now, about an year later!

I had this in my rear brakes, but after a pad change it went away

I'm going to work on the breaks once the sun comes out, I'll take photos of what I'm doing, so they you guys (and gals, if there is any) can see if it helps
