Where can I buy a brake booster check valve for a 1st gen? I'm having a tough time getting my brakes dialed in, really don't think its being effected much by the lack of a check valve, but want one on the truck anyway.
I've got the factory booster and M/C on the truck, with a Speedway proportioning valve. I've got Toyota hubs and rotors on it, with the Mitsu front calipers, and a Mopar 8.75 rear with Aerospace Components disc brakes out back.
I've got a really weak, low, pedal, even after repeatedly bleeding the system.
My brother thinks I may need an M/C with a bigger bore, but I note the Fordubishi is using the stock set up on his which has a big Ford 9 inch rear in it.
Any advice would be appreciated, and especially who carries the check valve...
