#1 IRS + rear brakes S1

Post by ralphr1780 » Sat Apr 30, 2016 1:00 pm

The IRS is on the floor, radius arms removed.
Have overhauled the brakes (original S1 setup).
Two questions:
1. The bleeders would enjoy easier access if mounted on the inner side calipers by the diff, than as originally mounted on the outer side ones by the shocks. Any reason why this should not be done?
2. Thinking of putting the IRS back on the car first, then mounting back radius arms and shocks, guessing it would be easier to manipulate this way. Any obstacles against such procedure?
Thanks in advance for guidance.

Fit remote bleeders either ready made or make your own. Makes the whole process so simple: http://www.fossewayperformance.co.uk/re ... asy-bleed/ and viewtopic.php?t=2121

Depending on caliper, line flare and bleed nipple type (some used ball bearings) you can't just swap brake lines and bleed nipples, even if threads seem the same, because the ports may be machined differently at the base.

Peter, the calipers ports looked the same on the 4 calipers.

Another vote for remote bleeders. I'm not sure that they would be a lot easier to access inboard although I agree that having to remove the front shocks to bleed them is irritating.

You can mount the IRS with the springs off, but it doesn't make it easier to install with them out.

I can't visualise exactly what you want to do with the radius arms, but I think you will have trouble installing the rear radius arm bolt with the hub carriers on.

Personally I always fully assemble the IRS then install it. For one thing you have a lot better access to check that everything is tight and properly installed.

Thanks Andrew, have mounted the bleeders inboard and they become of pretty easy access. If i had to install remote bleaders i would rather route these to the top of the irs for access through the trunk cover, guessing that locating these below would still keep entraped air.
As for the question of fitting the irs to the body without the front shocks and radius arms that is just considering to make lighter and less protruding. Hub carriers would be fixed but not fully bolted, ready to be loosened for fitting the radius arms thereafter.
