    Anyone have problems getting new brake pads to fit inside the calipers? Is it OK for me to sand down the top and bottom of the brake pad?

    Are you referring to length of the pads? The inside pads were very very tight one mine. They fit, but it took a few tries to orient it

    Did you push the pistons back far enough to fit the new pads in place? If not, remove the brake fluid reservoir cap. Take one of the old brake pads and place it over the piston and use a C Clamp to compress the piston back. Moving the piston back will allow more room to fit the new pads in place.

    I saw a great tip that helped on my backs. Setup a bleeder tube and just crack the bleed valve open. This lets you push the piston in much much easier

    You shouldn't have to sand , shave , or grind any part of the pad. There meant to be tight, make sure the pads are not cocked. I'm not trying to insult your intelligence by any means, just takes a little persuasion. Mine were tight on the fronts. Good luck

    Not to disagree with you, but you dont need to crack the bleeder to change pads, just use a good c-clamp. Don't want to introduce any air at all:cool:

    Is it ok to push the fluid backwards into the reservoir? Some anti lock brake computer systems don't like that.

    I’m not sure if it’s just the north east salt air, But after three years this thing is a bit rusty. It takes a pair pliers to get the old ones out, and a little ball peen hammer to get the new ones in. I just did the passenger side and took it for a drive and didn’t die, so I’m going to repeat the process with the driver side.

    I’ve only done this once before, and it was several years ago, with an 02 tundra. I don’t have much intelligence to insult.

    This is the edge I want to sand

    Sand or wire brush just to clean it up. I wouldn't reduce the caliber material any.

    Maybe round the edges a touch on the new pads.

    Haven't heard it being an issue with the Tundra. If the Master Cylinder reservoir is full, it can be messy as the fluid can be pushed out into the engine bay. If full best to lower level before pushing pistons back.

    Of course you don’t want air.

    What i did was put a c clamp on it, open the valve slightly as I tightened it, then i closed the valve so that it would not draw any air back in.

    It’s not a good practice, that’s for sure.

    As stated earlier, when compressing the pistons, open the bleeder. After a brake job, you should flush the old fluid out anyway. Should be done every couple years regardless of pad change out.
