hello everyone!

just wonder how hard itis to replace a brake hoses on 850 turbo?

 

It isn't all that bad unless it is rusted pretty bad.

 

However, if it is rusted, you're on the Dark Side.

This is one job I gave up doing myself. The connection did not have external rusts but were hideously corroded on the inside. I used flare-nut wrenches (the best tool for disconnecting soft metal fittings & connections) and the connections stripped anyway. I then resorted to a 10WR vise grip and had exerted a giga ft-lbs of force to no avail.

Reaching the rears can be a nightmare. The right-rear has a connection right on top of the delta link control arm and it is hard enough just to reach, and there is a plastic bracket getting in your way. The left-rear can be just as bad, you cannot even see the connection without bending your back for 360 degrees[:@]. The hoses only had minor superficial cracks so I decided to let them go for awhile.

If you encounter the same situation, I believe someone within this forum may have a magical cure for it. The 850 members are extremely knowledgeable & posses excellent skills (many of them probablydo better jobs than generic town shops or franchise garages).

Best of luck to you & happy holidays.

If there is rust, clean the connections well with a wire brush (or wire wheel mounted on a Dremel tool) Then spray the area with a good penetrant (I prefer PB Blaster) The connections should then come apart easily

 

You mean the brake lines?

They are hell. I rounded the nut pretty bad and couldn't get it even with vice grips and a flare tool. In the end, I took it the mechanic and he had to torch that guy for quite a while before it finally came loose.

The problem is that the threads are bronze/copper (I forget which) and the caliper is cast iron so over time, the two metals fuse together...

 

My fronts came off nicely with a little PB. The rears... well I ended up cutting those.

Glad to know I wasn't alone.
