How to Rebuild Front Brake Calipers : How to Properly Bleed Your Brakes

you sound like Dick Van Dyke

Also if you have not worked on your brakes for a long time, your bleeder will break off so this always works for me heat the caliper right next to the bleeder with propane torch about 2 min on 2 sides of bleeder, just heat up the caliper only dont try to heat the bleeder, then let it cool for about a min then use a 6 point wrench or socket and it should loosen right up. this also works for the back brake cly,s buut mke sure you dont over heat them.

do you have to bleed all the lines (front and Back) if i take out my front caliper ....do i have to bleed the back breaks too...thats what im really asking please write back . ty

I know little but I dont think so, but some say you need to replace brake fluid every two years cos it gets sour from oxygen and makes rust , but my mecanic says just replace it when replacing pads.

@orangestoneface Your mechanic is on the right track, but slightly off. Your average brake fluid is very hygroscopic - it loves moisture, and moisture causes corrosion. Water also has a much much lower boiling point than brake fluid. Your brakes work because fluid can't be compressed, but when dirty fluid is overheated in a panic stop for an example, the water will boil and create a compressible gas. Your brakes are now useless. Brake fluid bottles list DRY and WET boiling points btw.

@DeffRo Generally not, but its a convenient time to change fluid in the entire system. By removing a caliper you only introduce air to that section of the circuit. Sometimes people get distracted and allow the reservoir to run empty while bleeding, or opening the fluid circuit. Air is then introduced into the master cylinder and the whole system needs to be bled. Our expert also failed to mention that its important to cap off the open line as gravity will cause fluid to escape.

How does air get into the line?I dont know much about cars but this sure will help me someday.
