Drop spindle brake hose issue

m4co - February 2nd, 2015 at 12:42 PM

Hi all,

Has anyone had a issue with the brake hoses when using 2.5" drop spindles with a standard beam? I installed a pair and it pushed out the the drums to where at full lock there is strain on the brake hose.

Roughly measuring the hose on the car I think they are the correct 65' hoses and are about 450mm. Would it work if I used some T2 1950-55 hoses that are 490mm long. As in, would it thread in the brake cylinder and hard line?

I'm just worried that it's EMPI, anything that I have got from them isn't very good quality.

You hit the NAIL ON THE HEAD there

who supplied you the drop spindles they should be able to tell you what length you will need

Had a similar problen with a drop/disk brake conversion,needed about an extra 6 cm from memory.
Trip to the local brake guy sorted it out. 2 new hoses of the correct length.....

does your beam still have the steering arm lock stops

Looks like a link pin front end, no steering stops.

Hmm, looking at that I'd say that even a std spindle would give you the same issue. If you un do the hose and hold it at the point the drum on a std spindle would sit then see what happens.

LP beams have no steering stops as the LP knuckle acts as the steering stop.

Upto 64 were 470mm, 65-66 were 440mm and 66> were 380mm

Not sure why the 65-66 were a bit shorter for only a short time but looks like 470mm is what you should have, altho still towards the end of it's travel by the looks of your picture.

Maybe get Enzed to make you a pair?

Problem fixed!

The chassis is a '65 and had 450mm brake hoses, I ordered 490mm hoses and they are the perfect length now
Replaced the back hoses as well while I was at it.

Good News man

You will need to rotate the hose to solid line join so that the hose doesn't loop downwards. This was a fail I had to fix when getting my RWC so thought I best let you know in advance

That first pic in "problem fixed" looks like you have too much toe out on turns. Do the tyres rub on the floor pan? I have a set of dropped spindles on my Drag Car and had the problem with too much turn - noticed a small casting on the spindle- can't remember if it already drilled and tapped or if I did it- but I have a 6mm bolt screwed in it and it fixed too much toe out, so no more tyre rubbing, fixed the brake hose problem as well.The head of the bolt limits the amount of turning of the spindle.

Thanks for the heads up!

I did have too much toe out with the origional spindles but I think it was due to worn out tie rods, once I replacded the tie rods and now with the drop spindles installed the wheels don't touch the pan any more.

This is how it was with the worn tie rods and origional spindles.

Hi

It can be tedious but you can make lock stops by fitting a longer bolt in the leading brake backing hole, if it protrudes enough it will limit lock, VW did from the factory.

It can be tedious because you have to keep trimming the bolt down to the correct length.

On second thought the area where bolt would normally hit might have changed with drop spindles

nbturbo - February 18th, 2015 at 08:07 AM

You are correct Steve- the bolt is nowhere near a normal spindle would be. Looks like the dropped spindle has this small casting just for using a limiting bolt. Was lucky with mine that a 6mm bolt was just right.
