Older rear-wheel drive Volvos eat front brake pads. In city driving, I would average 20 - 25,000 miles max on the fronts. Since most of the effort is on the front brakes, the rear pads last significantly longer. I've had 4 Volvos, 240, (2) 740s and a 940 (current) The rear pads will get 100k. If you car is about 100k mileage and you're doing the front, I'd recommend doing the rears too. I've had better life with ceramic pads, but they tend to squeal. Volvos dust badly also, and dust seals are not recommended. Eagle One makes an all-wheel cleaner for about $5.00 USD that works very well.
The manual on the 2004.5 5cyl s40 Volvo says every 7500 miles
At least every 5000 miles to 3000 miles
PS should be 18000 miles and brake fluid about 30000 miles PS should be 18000 miles and brake fluid about 30000 miles
There is no set time or even mileage to change ANY brake pads. It depends entirely on the quality of pads and how you drive. -You should check them every 6 months and when they get down to 3/32 of brake material that's the time to change.
once a year
It depends on the brand of brake pad and your driving habits. Normally, you'll get somewhere between 30,000 - 50,000 miles from a set of pads.
There is no magic number as to how often you should change your brakes. Brakes will wear down differently depending on the make of the brake and they will start squeaking so you know that you need to change it.
There is no set time to change the pads. How often depends on how you drive. They may last 20,000 to 80,000. Inspect them every so often and listen for the squeal of the warning device. Replace immediately if you hear this.
The make and model of truck doesn't matter. When the shoes get down to 1/4 inch, you replace them.
When they wear out. Can be between 10,000 miles and 100,000 miles depending on driving habits.
brake linings should be checked at 15,000 and 25,000 miles and then every 5,000 miles after that.
Read the owners manual. It has that information.
