Is this the end? 180k miles, £3k+ bill for suspension and universal joint?

enuff_zed said:Multi-pistons set in a circle, acting on alternating discs of rotors and stators. The 'pads', if you want to call them that, are multiple sections, linked together like a jigsaw to make a circle.Pondrew said:Do they have disks all round? Or drums on the back?enuff_zed said::lol:
The pistons compress the whole assembly, pushing from the inside, outwards. The stators are free to move in and out and all the various parts clamp up tight together when the brakes are applied.
The inside of the wheel has raised square sections which slot into corresponding cut outs running across the rotors. The stators do not protrude so far as obviously you don't want those fixed to the wheel.
To fit a wheel you first have to use a multi-pronged 'spider' to align all the brake pack components, then apply the brake to hold it all together while you slide the wheel on.
The brake units are only fitted on the main wheels.
As the brakes wear, the pads and stators become thinner, meaning the overall width of the assembly reduces. A pin is attached to the innermost row of pads and protrudes through a hole on the inner face. After every flight the pin was checked and when it became flush then the unit was replaced.
The Tornado has two separate hydraulic systems. Some major components were designed to use both systems (double piston actuators etc). This allowed for the failure of one system whilst still allowing control to be maintained.
The brakes were not deemed a vital component and were only operated from one system.
In the event of failure of that system, the Central Warning Panel would alert the pilot and on landing he would make greater use of aerodynamic braking, thrust reverse buckets and, if required, the arrestor hook which was on a simple torque tube to force it down when released.
I hope that has furthered your education a little. :wink:
Sounds like a lot of fun and interesting tech. You think the nice men with guns at the entrance gate would let me in to have a play

How soon do you need it done?pvr said:enuff_zed said:
That is great - there was a “misting” entry on the last MOT and that probably means that it won’t go away by itself
This knuckle bolt (somewhere in the rust pile) and the spring assembly worries me
Happy to do it for/with you.
I have the compressors etc.
Obviously do both sides at the same time and unless done recently I would suggest new bump stops and top mounts at the same time.
Possibly drop links too, but I'd be happy to buy those off you if not needed.

No rush, MOT has expired and using the winter to get it ready for it by tackling the list of items to be done. Have ordered the starter motor as well to tackle that one. Just never done a suspension job
