I recently took the 1986 Peugeot 505 Gas Turbo up a mountain to do some hiking.
On the way down I experienced severe brake fade. After getting down the hill, the brake pedal was really spongy and had little braking effect.
I pulled over and checked the master cylinder reservoir and the fluid was full and there were no leaks.
After the brakes cooled down, they seemed to work fine. For awhile now, the steering wheel would shake when I applied the brakes over 40 mph.
Suspecting the rotors, I measured them and they were down to 15 mm. Mine are vented non-ABS.
I think the minimum is supposed to be 18mm.
I purchased new discs from Western Hemisphere.
I also purchased wheel bearing rebuild kits since I had to take the hub off to replace the discs.
I'm putting it all back together, but I confused as to how to torque the hub nut.
The Haynes manual says to tighten the hub nut to 30 lbf ft, then loosen it and re-tighten it to 7 lbf ft, then loosen it 1/8 turn and lock it.
The Peugeot workshop manual says to fit the nut backwards without the washer and tighten and then remove the nut and fit the washer and tighten the nut to 207 lbf ft.
Which procedure is right?
It didn't seem that the nut was that tight when I removed it. It took very little effort to remove it originally.
On the other hand, when I tighten the hub nut to 30 lbt ft, the hub was still very loose on the stub axle and moved around a lot.
