I have a trailer that I am having a hard time getting the brakes bled correctly on. The left side of the trailer is giving me problems. I just got this trailer 2 weeks ago and when I picked it up, there was no brake fluid in the reservoir.

I have tried using a vacuum on the caliper with a hand operated pump with no luck. I talked to a very experienced MC mechanic who said that there is very little chance of there being debris in the line and to just raise the tongue and let it gravity bleed. So far, nothing has worked.

I have a compressor based vacuum pump en route, but I also wanted to see if anyone else had experienced a similar issue or if anyone had any suggestions.

For the record, it is a MC trailer and is about 2 years old.

search on bleeding brakes and look at the hits. there are some references with links to pictures. basically it is a 2 person job if the lines themselves are dry. good luck.

Here's the link. I've done mine a couple times with no trouble.

Get a bleeder vacuum pump...mighty vac makes one....makes initial bleed out and also changing fluid every couple of years very easy.

also inspect the brake lines from the drum/caliper all the way to where it meets the master cylinder. I found a spot in one brake line that had been flattened and fluid was not passing thru. Prev. owner must have run over something big like a rock or log and smashed a section. Difficult to see the damage until after I took the boat off the trailer.
