wvzj Posted February 10, 2014 Share Posted February 10, 2014 I was just wondering if anyone had any experience with this kit. P# DDBXJ2 Heavy Duty Master Cylinder Kits for your XJ model Cherokee! These are a direct bolt-on replacement! Sold Individually. Kit includes a new master cylinder (1" bore) and a new dual-diaphragm brake booster. Works with and without ABS brakes. DDBXJ1 has an 1 1/8 bore Link to comment Share on other sites More sharing options...
Incommando Posted February 10, 2014 Share Posted February 10, 2014 This is supposed to be a really good upgrade. I wish I knew someone with experience with it. $421 here http://mudflaps.com/i-13978043-crown-automotive-ddbxj2-dual-diaphragm-booster.html Link to comment Share on other sites More sharing options...
wvzj Posted February 10, 2014 Author Share Posted February 10, 2014 I googled it but couldn't find anyone with first hand experience. Link to comment Share on other sites More sharing options...
ggcnash Posted February 11, 2014 Share Posted February 11, 2014 I think this is the same thing as the bobs upgrade JP magazine did an install and review on that one not sure but I know my 96 booster is a great upgrade and picked it up for 25$ Link to comment Share on other sites More sharing options...
wvzj Posted February 11, 2014 Author Share Posted February 11, 2014 I did the 96 upgrade on my 86 I use to have. It does make a noticeable difference. Link to comment Share on other sites More sharing options...

wvzj Posted February 11, 2014 Author Share Posted February 11, 2014 The only benefit to the kit is that you wouldn't have to make a spacer for the firewall or grind the rod flat for the brake switch on early MJs and XJs. But I still don't see where the extra cost factors in. For $180 you can get new Raybestos MC and booster from Rock Auto. Link to comment Share on other sites More sharing options...
ggcnash Posted February 11, 2014 Share Posted February 11, 2014 The plate is on stock just pull it at the JY when you get the booster like I said 25$ forget 421$ or even 180$ save it for other upgrades Link to comment Share on other sites More sharing options...
1989 Eliminator Posted February 11, 2014 Share Posted February 11, 2014 Definatly a huge difference! Here is my write up. http://comancheclub.com/topic/39437-1996-xj-dual-diaphragm-brake-booster-conversion/ Link to comment Share on other sites More sharing options...
wvzj Posted February 11, 2014 Author Share Posted February 11, 2014 For me it was just easier to make my own spacer. I'd rather have the peace of mind with a new booster. Link to comment Share on other sites More sharing options...
