disc brake conversion Costs
Here is what I have discovered as my builds have progressed :
I originally purchased a 1/2 ton 2 wd 91 burb, I used the front crossmember with my 6 cylinder springs, ordered all the front end parts from Rock auto and rebuilt the whole thing for $150.00 in parts so lets say I bought the front end only and did the same thing $200.00 front crossmember $150.00 rebuild front end parts total cost $350.00 5x5 lug pattern good solid front end. If you were going to drop your truck you would still need the front end but would spend an additional $260.00 with freight for spindles. $ 610.00 If you are going to lower the front end one could just round up the parts and use your stock crossmember purchase 73-87 lower A arms + the drop spindles as shown below. You do not have to do the crossmember swap in this example: $260.00 2.5" drop spindles with freight $ 36.00 for 2 new disc brake calipers at O'reileys $ 80.00 for 2 new disc brake rotors with hubs 5 x 5 $ 60.00 New wheel bearings both sides (estimate) $ 16.00 New bolts for the disc calipers $ 20.00 pair of used disc brake dust covers $ 40.00 Used lower A arms 73-87 or 91 burb $150.00 rebuild front end parts $ 662.00 You still of course will need a vacuum brake booster and master cylinder SUMMARY OF COSTS: Crossmember Cost : $350.00 (might still need new brakes) Crossmember + drop spindles: $610.00 " " Drop spindles/new parts : $662.00 " " Purchase kits online for ? $_______ I am sure I missed some things but it can be a guide..........or starting point ps when I used the $200.00 crossmember cost it is just a estimate, if you buy a complete donor vehicle cheap enough the cost of course is less. You still of course need power steering pump and gear, pitman arm, vacuum brake booster, master cylinder, proportioning valve....Kieth ![]() Last edited by kieth; 09-17-2011 at 12:14 PM. |

Re: disc brake conversion Costs
Great comparison.
Your $200 front crossmember could be purchased even cheaper. (I scrapped two complete disc brake crossmember assemblies,... because I couldn't sell them for $50 each) Year specific drop spindles will save you a little money when it comes to the steering parts. This allows you to use your original center link and original style tie rods. (no need to purchase $50 tie rod conversion sleeves) You think the same way as I do. Most parts need to be replaced. Disassemble, inspect, and rebuild either your front suspension or a donor suspension. There isn't really too much I like to re-use. Even the master cylinder needs to be replaced with new. A used proportioning valve can be re-used. I don't think 73-87 a-arms are a must. You can re-build your stock 60-72 arms. But,... 73-87 rebuild parts like cross shafts, bushings, and ball joints, might be so much cheaper than the earlier parts,... that they will pay for the better rubber bushed 73-87 a-arms. Donor vehicles DO save money. You get all the P/S parts, brackets, hoses, etc. (plus bolts, nuts etc)

Re: disc brake conversion Costs
thanks, since I am getting ready to do another build I thought writing down the costs would help me decide which way to go. Wish I could find some of those $50.00 crossmembers.
I am in the process of installing rebuilt components power steering pump, steering sector, vacbrake booster and master cyclinder...if you have cores these things are pretty inexpensive will update this thread after I buy some junk cores and get my $111.00 steering sector core deposit $ ?? brake booster deposit $11.00 power steering pump deposit..... couldn't find my receipt |
