Time: 20:06:14I need this soon!
First on the list is all the parts that should be replaced anyway, as they wear out and are likely already gone on the incoming parts. The wheel bearings, brake pads, brake hoses should be replaced. The brake discs should at least be turned, or replaced if too thin.
Parts that will need to be obtained from a donor car – either a 5-lug 924 or a 944 – are the brake master cylinder and booster, front discs, calipers, hubs, and spindles, and rear calipers, discs, hubs, and brake backing plates. Additionally, the hard lines that bolt up to the rear calipers should be obtained, though they can be bent from new line if necessary. For street cars, all parking brake hardware including both parking brake cables must be obtained also.
The front spindle/steering knuckle is different, and must be replaced as a unit with the hub and caliper, but the strut and the A-arm is the same, except for early 924’s (77 and earlier) which use a smaller balljoint. However, the later balljoint with the larger shaft can be swapped in without replacing the A-arm, as the balljoints are replaceable.
In the rear, less work is necessary. The backing plate which supports the caliper bolts on in place of the backing plate of the old drum brakes. The new hub which supports the disc slides on in place of the drum. However, it is adviseable, while the assembly is apart, to repack or replace the rear wheel bearings as mentioned above.
Finally, care should be exercised in the selection of the brake master cylinder. The 924 brake circuit has an X-split (diagonal corners of the car connected on the same circuits), whereas the 944 has a TT-split (front and rear on different circuits). If a 944 M/C is used, the brake lines will need to be re-routed to have the proper proportioning of the brakes front-to-rear.
If any one has this and can email me ASAP that would be great! Thanks in advance!
