Replacing brake pads and brake discs
« February 01, 2019, 10:35:10 »
Hi guys. In the past couple of weeks there has been a strange rumbling noise coming from my car when breaking. Today I decided to remove my front right and back right wheel to have a closer inspection. The pads look like they are worn all the way down so defiantly need to replace them. Would the same be said for my discs?

I changed the rear pads on a Nissan Primera 2004 before but found it to be quite time consuming. Also run the risk of damaging my break fluid lines.

First question is how much should it cost for a garage to replace pads, discs and labor. Are the pads hard to replace myself?

Concerns with going to a garage are being overcharged and getting cheap quality parts. Few pictures below. Cheers

I did front pads on fd a few weeks ago.

There is a post on here with vid detailing steps.

I'm no mechanic and took me total of all of 45 minutes, including having a brew.

That included jacking up, remove wheel, take off calliper, push piston back etc etc.

Never done back but recall you have to wind piston in. One of the more able should be able to confirm.

45 minutes is pretty good for two pads! Well coppared to what it took me to do two rear on a 2004 Primera  :lol:

I do have a wind back tool for the piston. Was a nightmare on the Primera.

What kind of noise should I be hearing when either need replacing?

Thanks for the guide link. Will give it a look

You could measure the thickness of the disc. If I remember correctly new disc should be 26mm. And need replacement when 24mm.  Not sure if the numbers were right but workshop manual told to replace discs when they are worn 2mm. But personally I would replace the discs also based on the pics. A visible lip on the outer side...

No need too wind the rear caliper, as the handbrake is a drum brake. Just a normal old school caliper. I believe the newer calipers, where piston needs to be turned, came with the GD model.

I think I'd go for the total overhaul, rotors, pads and you'd be checkng the caliper guide pins, cleaning those and lubing .

For rotors I'd be looking for a pair that are treated/coated to slow down the corrosion

If you don't know what you're doing, may be worth the $ to pay someone to be safe.

Excellent thanks guys. Will ring a few garages and see what the best price I can get with fitting. I reckon I could do it myself but it is quite time consuming for someone not experienced

DIY. Better to spend two hours fixing your car than sitting infront of your tv or computer. It only takes blood, sweat and beers. Here is some encouragement: :link: Etujarru..pdf - Google Drive

I'm not experienced and did front pair in 40 minutes.
Not done rears yet but expect may be same to hour.

Watch vid...... Very straight forward.

Cost 16 for set of pads on special, retail think circa 54.
Would expect garage to have been in region of 80 to 100.

I measure the thickness of my discs with a micrometer, and I've always found that by the time the pads have worn down, the discs are fairly close to minimum thickness, hence I've always replaced them together. Consider changing the caliper slider pins as well. If one seizes up you'll end up wearing your new pads/discs out prematurely. Squirt some penetrating oil on the set screws holding the front discs on, and use an impact driver with a good fitting bit to get them off, the metal is really soft and once the heads get chewed up you'll have to drill them out to get the disc off. To remove the rear discs, don't forget to release the handbrake and slacken the handbrake adjuster through the rubber bung in the disc. Don't use excessive force to pull them off or you might pull the brake shoe retaining pins out through the brake backplate!

Make sure the little lever inside the rear brake that the handbrake cable pulls on moves freely. If it has seized up or is stiff, you will have to try and clean it up and apply copper or aluminium grease to the pivot points. If it does seize up, it holds the handbrake shoe rubbing against the inside of the brake drum, so the shoe lining wears out and you get a groove worn inside the drum. The handbrake lever also becomes very slack.
