Just wondering if I should bleed the system when I change my caliper. Any input would be appreciated. Thanks in advance.

 

Better safe than sorry. I'd say bleed it.

 

Damn

 

Once being the idiot I am, I changed the master cylinder on my 90 integra and didn't bleed the system. It still braked the same for a year until I bled it

 

Whenever you have to disconnect any of the brake lines you should do a full bleed of the system.

 

Any time you do anything more than simply change the pads on a street car, you need to bleed the system.

EVERY time you open any of the hydraulic lines anywhere in the brake system, you MUST bleed the system.
of course that doesn't mean simply pulling the cap of the MC to top off the fluid, but any time you open any other part of the system, you introduce air and moisture to the lines, and they must be bled for proper operation.

 

How do I do it and what kind of brake fluid should I use?

 

speed bleeders!!!!!!!!!!!!!

 

Please find and read a service manual, or search for brake job writeups on the forums. there's TONS of info out there.

Edit...

honestly.. based ont he questions I've seen here, I recommend you take the car to a professional. Saving money by doing it yourself is nice, but it's dangerous to work on brakes when you don't know what you're doing.
A few bucks to replace a caliper and bleed the brakes is much cheaper than even the ticket and insurance premiums you'll have to pay if you screw it up and wreck your car.

 

Okay thanks guys, sorry for the stupid question

 

Actually, whether you open your Brake Fluid cap or not, over time you will need to change the fluid.

 

Just bleed the caliper you change. You'll be fine.

 

except when the air from that line reaches a distribution point...

 

bleed properly, unless you want air in the system and have your pedal sink to the floor.

 

If your going to do anything that Involves the calipers and the brake master cylinder and changing brakes to changing brake fluids and changing washers and opening the bleeder valves, Yes you will have to bleed the whole brake system.

 

it is recommend because you get air in your system better safe than safe but yea like everyone said here is correct
