can someone give me a step by step guide on how to replace my brake calipers on my honda accord 91? is it mandatory to bleed the brake line if you have to change your calipers?

 

Yes you should bleed your new brake calipers, otherwise you'll run into problems. Its pretty straight forward, remove caliper, remove flex line + washers, replace with new one. Bleed- get someone to pump the pedal 3-4 times and hold, crack open bleeder screw, watch for air bubbles, repeat until you get a solid stream comin out. hope this helps.
