The car inspection failed due to a leaking rear brake cylinder. Does anyone know how to replace one or have any tips or the cost to replace the two rear ones? I didn't want to pay Crappy tire 1000 bucks to fix all the ****, so i'm going to do it myself and take it back when it's finished. Anyone have any experience with this?

 

well first off wheres the fluid leaking? on the brake line or the brake cylinder or caliper?

if its just on the brake line where it screws into it then simply try to tighten the line. they could just be posibly loose. ive had that happen before.

if you have drums in the back then replacing the brake cylinders are very easy with a few brake tools..... and if you have rear disks those are a bit more of a PITA to replace.

 

Cylinder replacement is not a $1000 job. Shop around for a place that will just replace the cylinder if you're not going to do it yourself. A lot of people like to replace both sides at the same time (the theory being, any brake work, do the same to both sides so you won't have brand new stuff unbalanced versus the old stuff) but it's not absolutely necessary if the only problem is a leaky cylinder. Do take the other wheel off and inspect it for leaks or other problems.

As far as how to replace, it's simple.
Get a 10mm tube wrench (also called a "flare nut wrench"). Do not attempt to remove the tubing nut with an ordinary end wrench.
Jack up the car and support it securely. Take the wheel and brake drum off.
Loosen but don't remove the tubing nut.
Remove the two bolts holding the cylinder.
Remove the tube and take the cylinder out. Immediately install the new one before all your brake fluid runs out.
Put the brake drum and wheel back on.
Bleed the brakes.
Test drive carefully.

 

also when you replace it jack the rear of the car up as high as posible and leave the front nose down as much as posible! this will keep gravity from draining out all your fluid and making a big mess and also prevent air from running back in the lines as easy... it just makes it alot easier when bleeding the air out of the system!

 

Yeahh i really think that Canadian Tire was trying to screw me over,
I pulled both rear tires and checked the brake drums, and no leaks,
didn't even look like they pulled the center cap off the hub, still a thick layer of dirt around it...
And it was completly dry underneath.
I wasn't going to pay 1000 for new tires and to fix a brake cylinder...
I think they were trying to pull a fast one on me.
