Question about 2004 Pontiac Grand Am

4 Answers

The front right caliper on a 2004 grand am is leaking at the banjo bolt. I got a brand new caliper to replace the old one. It came with three washers.It's the first time I've seen washers ona caliper

My dad said to align the washers as to "cup" each other, he compared them to bowls saying the opening should be facing each other, it creates some sort of vacuum to the seal. Is there any merit to this or is my dad full of it?

Wait, are you talking about the brake hose-to-caliper washers?

you just need one washer on each side of that brake hose before you bolt it into the caliper housing ~ my washers came flat so i don't really know which ones
you're talking about

edit: so you only need ONE washer on each side of the hose, the 3rd was an accidental EXTRA

they're usually one-time use crush style so if you were trying to torque this down more than once, you may have to get new ones

    Yes, sorry that wasn't clear. It's leaking where the hose connects to the housing. There weren't washers on the old one, so I tried without washers, it leaked. So I put all three on. Two on bottom one on top of the hose connector. It still leaked. I adjusted the washers how my dad told me too. It seemed to be fine when I tightened it down, but 5 miles into the test run the light came on and I lost pressure in the brakes.

When you replace the main flex brake line there is a washer that goes on both sides of the hole the bolt goes through. The third washer was probably an accident. Not sure, but usually there are only 2.

    I put it on without the washers, the old one didn't have them so I thought maybe they weren't necessary. It leaked a ton, so I took it off, replaced all three washers. Still lots of leakage, called my dad, he said to put all three on so the concave openings of the washers lined up with each other, seemed to work great until I took it for a drive to make sure they were working before allowing my wife to take it to work on Monday. About five miles down the road the brake light came on and I lost pressure in the brakes. Should I just try the two, one on each side?

I've got a 96 town and country van i replaced the


The bolt that holds the line to the caliper is called a banjo bolt. It needs a copper seal on the top where the head of the bolt meets the line and one at the bottom between where the line meets the caliper. You should be able to get a replacement bolt and new seals in the HELP section of your local auto parts store, if this does not stop the leak there must be a problem with the caliper threads themselves and you might have to exchange it for another one at your parts store.

My front brake is leaking the brake fluid and i whant to fix it my self


first where is it leaking from is it the banjo bolt that connects the hydraulic fulid line to the caliper or is it the bleeder bolt check those to see if lose.. or is it leaking from around the brake pads if so the seals around the piston or pistons depending on the caliper. if so new caliper or find a junkyard. you will have to bleed the brake line of air after swaping caliper i highly suggest getting a power bleeder for removing air out of the lines keep in mind that you have to keep the resavor full of brake fulid awhile power bleeding...!

I changed a 93 ford calipers and they are leaking


if the calipers are leaking then they are defective.....

if the leak is at the banjo bolt "where the line bolts to the caliper" then you need new copper crush washers.

good luck

Please help!!!


You should have a crush washer on each side of the banjo bolt. You may be loosing your pressure to everything else by all the brake fluid leaking. You may have to go through the motions a few times before you see the fluid come out of the rear.
