i picked up a 5b ss complete with a jr xr3i tx in very good condition lately and i have familiarized myself with it by reading the manual cover to cover and dismantaling it to the chassis and back. after testing all functions i find the brakes weak (the rear tires do not lock up at all -is this normal ?) the servo i'm using is a z590 by jr with metal gears and high torque , not sure of the numbers though. the brake parts look good to me so i'm not sure as to what to do. install shims ? get a stronger servo ? or maybe get an aftermarket set-up such as tng ? . my 2'nd question is about the shocks, i was wondering if i can use motorcycle shock oil and if so, what weights in fr/rr or do i need to order online for 5b shock oil ? i thank you know for any help in these maters. what saz ya

As far as the brakes go, have you tried adjusting the throttle/brake linkage?
As far as the shocks go, 20w Motorcycle FORK oil was recommended to me. I've been running that in my shocks for about 2.5 gallons now, and haven't had a single issue/leak. It was also highly recommended that I lube all shock orings with Team Associated Green Slime lubricant during assembly/rebuild to prevent tears and wearing of the seals..

brakes
well i took it appart last night, inspected and cleaned it, there was hardly any wear so that was good. as a fellow bobbiest segested i installed an extra shim, added two small springs in beetween the calipers to reduce rolling friction (springs donated from a bic pen) and removed the spring from the linkage, it was replace with targon fuel line for extra firmness. i got test it out at the local 1/10 track and there was a remarkable improvement. 1 min. 32 sec's latter i wrap it around a catch fence post and blew up steering servo (complete with mushroom cload
lol) no spare so your parked. i pull out the t-maxx , do two laps and do the same damm thing !! i was like - dude-whats the odds :whhooo: but i had a sprare and life goes on.......

The breaks are no normal. I am running this throttle servo http://www.rcsuperstore.com/product_p/futm0043.htm and it has potential to skid.
