PITA, Here are the pages from the Factory Manual on changing out the front pads and disks. There is also a section on rebuilding the calipers (replacing internal seals, etc), that I don't think you need.

The "Caliper Service" is probably just a quick cleaning, lubricating the backs of the pads and the caliper sliders.

 

Unless I missed it in the manual pages above...you'll need to push the caliper PISTON back in it's bore in order to fit the new (thicker) pads. Use a small "C" clamp for the purpose.

Also, remove MOST of the brake fluid from the master cylinder reservoir first, or you'll squeeze the fluid right out of the top when you push back the caliper pistons.

It would also be a good time to bleed / renew your brake fluid throughout as well.

 

Thanks!

Now that's help! Annfan, if you're ever around Georgetown Ontario, beers are on me!

And thanks Max, great tips. My dad was a mechanic and I learned those things by his side. Tomorrow it'll be with my kids...

 

Hi I want to change the rear brakes for a disk brakes, I have a 2010 gv 2.0 4x4.

there are many kits in ebay but i dont know if is safe and posible!!!!

 

the drum brakes are fine. good chance you'll mess something up if you try to remove the drum system

 

I'd suggest starting a new thread on the subject.

Also beware of the probability that you'll need to change / modify or procure additional associated brake system parts like...ABS, proportioner, master cylinder, e-brake and alike to make it all work safely.

Your BEST bet is to find a wreck that has 4wheel discs (if there is such a thing for your model) and grab everything you need to make the swap. But then again, you have a 2010? I guess that you would have bought them factory installed if it were an option.

If you THINK you need rear discs, then you bought the wrong kinda' ride for what you are trying to accomplish, driving style wise.

 

OK Thanks!! almost all clear, they didn't came factory, and the option is only for the v6.

And is true maybe I dont need them.

The dealer sold all the 2009 inventory , this is the new one for 2010. Thats whats the dealer said.

 

Then a V-6 model wreck is what you need to watch for one day down the road.

Also, about 70% of a vehicle's braking effort is provided by the FRONT wheels. In other words your current up-front discs. To tell ya' the truth, you'd proly never need or FEEL any difference w/4 wheel discs unless you are doing some sort of hellacious towing, mountain climbing or autocross.

 

Yeah is rigth!, and maybe change the front discs for a bigger size?...I'll use a home trailer soon, its not so heavy ..I Think not more than 800kilograms..

 

A month ago I replaced the front pads on my '07 GV and I can offer some advice...

Make sure the new pads include shims as shown as Item 7 on Annfan's first diagram.

The new pads should also include new wear indicator clips as show as Item 6 on the first diagram. They install on each inboard pad at the bottom.

I used Autozone "Duralast Gold" pads and so far they have been excellent and generate less brake dust than the original factory pads.

The rotors were in good shape with no scores/run out/excessive wear so I left them on.

 

I just noticed a while back that EBC have greenstuff pads available for GV

I've had those on other cars, and they are HIGHLY recommended ! You will get more grip, more brake response, and be much less prone to overheating / pad fading.

 

For more brakes when pulling a trailer, it would be much easier and cheaper to modify the trailer for surge brakes than to modify the GV for disc or bigger disc brakes. A surge brake works by putting a hydraulic cylinder where the ball connects the trailer to the vehicle. When you brake the vehicle, it pushes brake fluid to the drum brakes of the trailer (you can get disc for the trailer but they need higher pressure than surge brakes generate typically). Last time I looked, a kit to add surge brakes to my boat trailer was a few hundred dollars. And a pretty simple bolt on operation.

ok im going to look Thanks!!!

 

caliper pin bolt coming apart

I've changed brakes on plenty of other vehicles but haven't run into a caliper such as the one on my GV. From the diagrams on the other post it seems the Caliper pin bolt threads into the slide pin. When I tried removing the caliper pin bolt from the slide pin metal shavings started coming out, making it seem the bolt was either stripping or coming apart. Has anyone else experienced this. I've already purchased the rotors and pads and would hate to take it to the dealer when its a pretty simply procedure. Thanks.
